I'm not much of a gearhead when it comes to music software/hardward, and I was not able to find any of the plug ins you mentioned with a quick google search.
I've received very positive feedback on the mix of my songs here at OCR and by some faculty at my school, so I guess that means you can put some faith in what I'm saying. I just opened my latest project, and here's the breakdown on the inserts for each channel.
21 tracks total, mostly synths, some instruments
EQs (channel, parametric, pass/cut): 27
compressors,limiters: 16
modulation (chorus, phaser, etc.): 5
delay/reverb: 3
stereo imaging: 2
Good mixing is straight forward: EQ & dynamic processing. Of those 27 eq inserts I had, 21 were a simple channel EQ (Logic Studio). Otherwise, find a compressor and a limiter. If you can use all of those, you win. Modulation effects can be used to improve the mixing, but only as the icing on the cake.
What I did: made songs, mixed them, got feedback here, repeat. Along the way, I read many of the articles you can find linked at various places on this site.
First lessons: endeavor to make sure all parts/instruments have their own slice of the frequency pie; that is, don't have two or more instruments competing for the same range. Learn to roll off or cut a lot of the low frequencies on most instruments - let the bass and bass drums have their space.
Don't spend too much time mixing on tired ears. Mix your songs on different sets of speakers and in different rooms (more a final step). Always alternate frequently between headphones and speakers (always!).
Take time out to listen to other songs while you are working. Save recordings of the whole mix every so often so you can see where you've been and where you're going.
Whatever you're working with, take the changes TOO far first so you can see where your playing field is. So often, you'll make little changes that, in your mind seems important, but are actually way off from having any real impression on the song.
I'll add anything if I think of it...
