one interesting discussion that I have had in the past was about mixing the overheads first or last. basically weather you should mix the overheads and add the close Mic's kit pieces to add a little extra punch, or mix the individual pieces first then add the overheads for a little extra ambiance. the latter, I find creates much more of a typical pop sound, the former I find, creates a natural drum tone. just a little thing you may want to try. when mixing drums though I find the most important thing is to get the kick to compliment the bass (guitar) and the snare to sit equally with the kick, the balance of these two pieces can make or break a mix, then mix the hi-hat, toms, cymbals etc. to sound great with the kick and snare, if that makes sense.
