eliminating mic "noise" post recording.... best EQ plug suggestions please...?

With mics, it's always best to get it as right as possible the first time around.... barring that, is the noise in the vocals or the space in between the phrasing?
 
If it's in between, the easy fix is to use the audio process to mute the noise..... just zoom in, drag the mouse to select the area you want silent, and process it.  Waa Laaa, perfect silence. I use this often to eliminate the room noise and vocal/mouth noises
 
If it's in the vocals, you can cut the lows with EQ but that may ruin the vocal quality.
 
Without hearing it, it's really hard to say... but sometimes, the noise is so embedded and loud/noticeable that it effectively renders the track useless.

Low-frequency plosives aren't hard to mitigate, because they're well below the fundamental frequencies of even a baritone vocal. Any EQ can do it, even if you have to stack filters to accomplish it. Using a spectrum analyzer, identify the lowest important frequency in the vocal track. It might be as low as 200 Hz, but your plosives are probably below 100 Hz. Fixing it will only require a 48db/octave slope starting at 200 Hz. If your EQ can't do 48, stack two 24db/octave filters atop one another.
 
Sometimes, though, low-frequency pops will have harmonics that extend up well into the vocal frequencies, so that even after filtering out the <100Hz stuff there's still an audible artifact. In that case, a multi-band compressor (e.g. Sonitus Multiband), dynamic equalizer (e.g. MDynamicEQ, my preference) or broadband compressor with a sidechain filter (e.g. Pro-C) can save the day.
 
With any of these methods you can usually be very aggressive in suppressing pops without hurting the performance, since the meat of a vocal track is in the 700-2000 Hz range.
 
Now, if the singer was really blowing into the mic, there's also a chance that the track is also distorted. If you just can't get rid of the artifacts no matter what you try, look for clipping. If the track is clipped, then you're screwed. Tell the singer to do it again, or live with a bad track. Or go all in and throw on some more heavy distortion, call it an effect.
 

All the tricks I've accumulated for editing, tweaking and generally saving vocals from the trash bin have been learned by salvaging my own mangled takes. I reckon if I can make myself sound passable, I can then confidently claim to make real singers sound great.

Waves de-breath plugin is pretty good at removing unwanted breath sounds in vocal recordings.

For other noise removal purposes I try and eq out what I can without damaging what I want to keep then run the track through Audition's noise removal processing. Like all noise removal, a couple of passes at conservative settings can be very effective and cause fewer artifacts from noise reduction than a single pass at more extreme settings.

Sometimes just a very tight eq cut can do the job. I am plagued by guitars (even Gibsons with humbuckers) picking up the wireless router signals and converting them to audio as two whining noises, one around 2.4KHz and the other around 5KHz. It's most noticable at high gain of course. A couple of very narrow eq cuts at the offending frequencies gets rid of the noise with almost no noticable side-effects.

I've tried removing fan noise with Audition. Like tlw says, it works better with multiple passes at mild settings. Having said that, even though you can pretty much eliminate it, there are quite audible (and unacceptable) artifacts at 100% elimination. So now my philosophy is don't even try to completely eliminate it, as long as I can get it maybe 75% of the way there I can put up with a little noise. If the track is competing with multiple other tracks it's not going to be noticeable at that level, except maybe during the silent parts of the track (and you can edit those). If it's a solo performance then I'm going to be more concerned, but I think if I was recording solo performances I would seriously think about ditching the idea of recording at home (which in my case isn't exactly ideal) and shelling out for a recording session.

I was able to rid the funk below ....exactly as described above....using TRacks Classic EQ....which I forgot I had on hand waiting in the wings.   I still have another artifact going on that is in the higher register... when I get this song uploaded...I will leave it to ya to hear it and see what ya think...thanks again for all the input  ;o)
