Meat Truck,
I've been learning a lot about EQ lately myself, and it's very important. Everything needs it's own space to sit well with the other sound sources. It's easy to have guitars, keyboards, vocals competing for good space in a mix.
Most tutorials tell you to start with the source and the mics before adding a ton of processing, but I performed a search on the DUC a while back and found this link to be very cool. Hope it helps.
