There's some useful general information at:

The best advice is probably to trust your ears and often less is more. On deck 
mixes you may often be best off doing as little as possible. Generally 
speaking a DJ mix shouldn't need compressing or EQing unless there's 
something in the mix which obviously needs correcting.

It's worth familiarising yourself with the spectrum analyser and 30 band EQ, 
you can draw your own eq curves if you want, but it's possibly easier to 
start with the 30 band eq. You can set which signal to analyse in the last 
tab, I find it most useful to look at the output most of the time.

It's worth putting all the sliders down to minimum and turning each frequency 
range up in turn to get a sense of which parts of the music they affect. It's 
similarly worth doing the reverse i.e. turning all the faders up to 0dB and 
seeing what effect a cut has. In practice this is the better way to do it. 
When in doubt, cut rather than boost frequencies. My general rule of thumb is 
- when it stops hurting, it's probably right. ;-]

Roughly speaking < 250Hz is bass frequencies. Vocal notes happen around 
1-2kHz, but be aware that all sounds have upper harmonics, most noticeable 
between 5-10kHz, this is also the most annoying region for hiss. Also watch 
out for bass rumble. JAMin allows you to pinpoint certain frequencies without 
destroying the energy balance across the spectrum, if you're careful. ;-)
