Hello, I'm new to music production and need help configuring and setting up my gear!

I can run my mic and guitars through the Roland as well so my mixer seems kind of useless now? Should I keep it? Sell it and save up for something better? 

It depends on what you want to do. Like 57Gregy said, you probably don't need the mixer unless you are recording with a band, drum kit or have lots of instruments/mics that you want to keep setup without having to swap them out each time you record for convenience/laziness.
 
I'm not too familiar with the Roland and its abilities as an audio interface, but if you don't need the mixer you could sell it and put the money towards a decent audio interface like one of the . Or maybe a control surface or the countless other tools available for making music. If you are new to this and plan to take it fairly seriously, you should plan to get the best studio monitor/reference speakers (not hi-fi) you can afford as well as studio-quality headphones, a decent large diaphragm condenser mic (for vocals and some instruments), good instrument mics and so on. Oh, and then there's a multitude of indispensable plugins that can sap all your money too - careful with those. You can end up with so many you can never find the one you want when you want it and will probably end up only using 5% of them. So yeah, if you don't need a bulky mixer, get rid of it and swap it out for something you do need.

I currently have a pair of KRK Rokit4 and Sony MDR-7506. Are these good enough? I read alot of reviews before I bought them(low budget) and I really like them both. I got a cheap microphone so that will probably be my next investment. What would be a good enough Focusrite to invest in? I will try to produce all forms of music genres to learn as much as I can.

First off, I'm making the assumption that you are a younger person getting into music production for the first time as opposed to an older person. So money isn't a plentiful thing. I'm also going to assume that you are a musical, creative type of person and haven't just randomly decided one day to get into this, try it out for a bit and then probably lose interest in it just as randomly. 
 
KRK Rokits are fine on a budget and will do for now. The important thing is to get used to their sound by comparing your mixes on them with other speakers you have - hi-fi, car, phone/Bluetooth, ear buds etc. If you're happy with them that's great! When you have more money in due course consider getting some higher end monitors and keep the KRKs for comparison when mixing.
 
More important is replacing the cheap mic because that's the device that the sound goes through first. It doesn't matter how high end your gear is in the rest of the signal chain your sound will only be as good as that mic. You can not polish a turd as they say.
 
As far as the audio interface goes; that's the next several components in your signal chain - pre amps, ADC/DAC, ASIO interface etc. so it is many things in one. So don't skimp on it! I recommend Focusrite only because I have used their gear for many years, they have a great heritage and, well their sound cards and components are good. Which one you may choose depends on how you intend to use it. Their Scarlet USB range will probably suit you. It's really down to how many inputs and outputs you want. Two analogue inputs is generally the minimum and will allow you to record in stereo or record vocal and guitar at the same time for example. There may be times when you need more. Many audio interfaces only have one pair of analogue outputs that you plug your monitors into - that's quite limiting. The more ins and outs you have, the more patching and routeing options you have. However, if you never have use for them all and are on a tight budget, it's a waste of money having more than you need.
 
The Scarlet 2i2 is the absolute minimum I would recommend for you. It gives you 2 mic/line/instrument inputs and two balanced outputs (stereo monitors).

I have a Acer T272HL 27" Touch Screen Monitor which I can angle between 30-80 degrees. Do you think this will benfit me in my music production? I'm thinking as a substitute for a control surface.
 
Also I have a Yamaha ERG 121 with 5 mics and Joy Turner with 3 mics. As a beginner I feel that these are good enough? Any thoughts? I really like the Joy Turner. I have a cataluna acustic too.
 
I don't think I will invest to much in plugins as I feel I have to learn more of the basics on sound engineering first.
 
Thanks a thousand for all the help!

I don't use a touchscreen, but I imagine it would be useful if positioned in the right place/way to reduce fatigue from stretching across a load of gear to reach it  I cut my teeth in studios with analogue consoles and tape machines so I like to have tactile control of as much as possible. It just works better for me pulling faders or turning knobs while listening with my ears rather than looking at a screen and listening with my eyes. Having said that though I have got very used to doing things with a mouse too. I think a touch screen may be a good compromise providing you remember to listen with your ears and not your eyes! At the end of the day, touch operation is becoming the norm and mechanical faders and knobs are so last century.
 
As far as your instruments go, it's so subjective. If you enjoy playing them and like the sound you make with them they are perfect for you. Once you get into playing an instrument e.g. guitar, you will inevitably acquire new ones here and there, probably never get rid of your old ones and have your favourites for certain tasks and an overall favourite too. At which point you have a collection of guitars hanging on the walls and can definitely say you are a guitarist!
 
Don't completely overlook plugins. They are very useful. Sonar does provide a hell of a lot of useful instruments and effects, but not everything you will need on your journey.
 
Good luck.

Well, 31 is still young by my standards and leaves plenty of time for a fresh start which I congratulate you on!
 
I am not familiar with that mic. It should come with a shock mount though, but if it doesn't you definitely need one and a pop filter/screen too.
 
Enjoy your music. Self-esteem is an important thing to build up and hold onto. Always take criticism constructively, but never assume that someone giving the criticism is right or actually knows what they are talking about. Some of the best advice you ever get may be critical. It is a really good idea to get to play with other musicians as soon as you can. The better they are, the better you will become and the more confident you will get. However, there is no substitute for experience. So keep going and build that up. There will be low days when you feel like giving it all up. Don't!
