The first thing you want to focus on when EQing is cutting out the bass. Unless it's a sub bass, you want zero bass sounds in that sound. And even things that sound fuller with a bit of the bass range, cut out the bass to make room for the actual bassline holding it down there. Especially with things like snare and cymbals. Depending on the snare, you probably want to keep things ~250Hz, especially if you like that low snare that's becoming popular in dubstep, but with cymbals, you can cut and cut and cut and nobody will notice. Same goes with a lot of lead synths -- especially with the buzzier ones, you can even get away with killing the fundamental, and the listener's mind will fill in the blank without them ever realizing it.
When you're cutting lows, make sure you're listening to the full track and not just the one sound solo'd. You can actually cut a lot more than you think you can. Something might sound REALLY thin by itself, but in context of everything else, sounds perfectly fine.
If you find frequencies that a sound doesn't need, cut them.. Be careful, though, because cutting highs and mids will change the sound much more than cutting basses. With most basses, kicks, etc., you should sculpt away the mids and the extreme highs, leaving the moderate highs mostly intact. It's the highs that you ears will actually notice, and unless you want an indistinct bassline just filling in the low end, you need those highs there for the ear to follow. That goes especially with kicks -- you want to keep the lows for the umph, and the lower mids for the crunch, and keep the highs there for the attack so you can actually hear it.
The only other big thing you should do with EQ is cut out frequencies in sounds that don't really need them to make room for more important sounds. If you've got background stuff with a foreground, melodic synth, first figure out what frequency range the melody is most prominently heard. (With vocals, it's usually ~1kHz.) Then, in most everything that's not the melody, EQ that part out just a little bit. Now that your melody's no longer fighting for dominance in that frequency range, it'll pop out a lot more without you having to make it really loud.
Also, use a spectral analyzer, especially on the master, to help you figure out what to do. Making sure everything has its sonic space is really important, especially when you add more and more instruments. And if there's a buildup in any given frequency range, a spectral analyzer on the master will tell you that. Just look for any large peaks, and then figure out what's causing them. Then you can either lower the volume on that, or you can cut those frequencies in other sounds that don't need them as much.
I can't give you frequency ranges or anything, because it really depends on the sound you're EQing. So just experiment, figure out what sounds good.
Note that sometimes, you're going to have to automate EQ (or just have separate EQ plugins turning on and off). You might have a section without a bass, so you want some other sound to have those bass frequencies so it doesn't sound flat. Or maybe some of your background synths come to the foreground in a section.
Also, look up sidechain compression. If you have two things competing for the same sonic space, and there's no way to EQ your way around it, sidechaining's the way to go. I almost always sidechain my bass to my kick, so that the bass ducks out when the kick comes in, and I usually end up sidechaining my cymbals to my snare so that the snare's highs pop out a little more.
