Although it may not be 100% realistic, most people use way less reverb on the kick than on the other drums (and sometimes zero). I use ProChannel EQ differently on each drum.
That said, I often combine toms on one stereo track and pan them in the drum plug in, but I know CJ and others will disagree with that. My set-up for audio tracks is usually 1-kick, 2-snare/sidstick, 3-hi-hat, 4-toms (stereo), 5-cymbals (stereo), 6-other perc (stereo). Although this layout began with tape when tracks were limited, even with unlimited tracks I dislike the clutter of tracks I don't really need. My console shows 8 active tracks at a time and I don't see the need for 5 tom tracks and 6 cymbal tracks.
I normally keep MIDI separate to make editing easier, but sometimes use a single MIDI track. Depends on your workflow.
