Got a few people to reply to here so will do soon, but I'll start with these:

How does one unmask two frequencies if they coincide?
EQ is one solution. Lets say we have cymbals and an acoustic. No eq, they both naturally kind of want to sit in that same space. They clash. One might slightly lean to the top, one to the bottom. Let them go there and eq them to just shift them in that direction. It might work, especially if the bands are quite wide and you can cut a fair bit without taking out too much of the sound. If the acoustic already only has a very narrow band, you might struggle to move it much. If you try and push them in the opposite direction, it probably won't work as well. But the better solution here I think is to re-record your acoustic. Use a different mic or change the positioning of the mic. You'll much more easily be able to move the natural position of where it wants to sit than eq can do. THEN you can eq to fine tune it the rest of the way and you'll be able to be much softer with your settings and it'll sound much more natural, smoother and better. That's how I see it anyway!

I realize I'm just talking about my own particular scenario, but I really don't *know* what kind of a mix I want until I have all the instruments tracked and laid out, therefore I don't know what any instrument *should* sound like in the end, until I start to mix.
That's exactly why I'm spending a LOT of time recording rough tracks and doing a very quick mix to see where they want to go. It's helping me so much and I KNOW I'll get a result that is ten times better this way. I'm learning so much about just this individual song doing it this way. I feel the need to do it for everything so at the moment, but I'm sure with practise, you'll need to do it less and less. But I can't stress enough the benefit of it.
The alternative is to try and get it right the first time. But if you can't get it to fit in properly, you better be ready to go and re-record it cause you'll get a much better result than trying to 'make it fit'.
I'll spend at least a good hour just tweaking with mic/mics positioning and amp/guitar settings (not including the initial l set up time) to get the right sound. But if I don't have plenty of rough tracks to begin with, all this time may be pretty useless (apart from the learning experience).
This is why I am now a big fan (now) of making rough guide tracks. It's worth the time, unless you have the serious experience, and even then, it's probably worth the time!
Also you mention not *knowing* what the mix needs to be like at the start - that's one reason I like the idea of the soundscape drawing that I put up before, and Danny's one (which I'm still looking into a little deeper, Danny, thanks for that!). Work it out in your mind on paper where things need to be, and record them like that.
