Not presets, per se, because I use more than just Pro Channel FX, but I usually find a combination of the following works well. Much of this depends on whether we're talking sampled drums/triggers or drums recorded live. The amount of bleed also determines a lot of what you have to pay attention to.
- EQ - filter out the highs and especially lows that you don't need/want. Don't forget to try different modes on the PC EQ
- Tube/tape saturation - I find the saturation knob in the Pro Channel is great for getting kick, snare, and toms with more "oomph!" If you want more, try the Cakewalk FX2 TapeSim on 15 IPS, crank down the output volume, crank up the input and the warmth.
- Compression- generally speaking, a compressor with a faster attack (like the PC76), set to it's fastest attack setting (or close to it), will tend to give drums more punch
- Gating/expansion- these can be great for getting rid of unwanted sounds in the drum mics, although to be honest, I usually just edit the tom tracks themselves to cut out the sound where my tom mics capture unwanted sounds. Toms are easier to do this with than kick or snare, since they are used more sparingly for a huge variety of beats
- Transient designer - the PX-64 percussion strip or the TS-64 transient shaper can be very helpful, too. These are designed so you can give your drum tones (or other sounds) more/less attack (the sharp transient when the drum is first hit) and more/less sustain (how long should the boom/room tone hold out for? For toms this can be very stylistic, but I tend to find most recorded/sampled toms need a touch more attack and significantly sustain.
- Reverb - really dry sampled toms may need reverb, where toms recorded with overheads and/or room mics may not
As for how to add them, I usually set them up in this order: Gate->EQ->Compression->Tube/Tape Saturation->Transient Designer, with reverb on an aux send.
Then I bypass them all, solo the tom, and enable/tweak in this order: EQ, Compression, Tube/Tape Saturation, Transient Designer, Reverb, Gate. (Gate is enabled last because it can sound a bit odd/obvious when the tom is soloed. Once I think I have the gate set right I switch to the next tom soloed, then to the toms in context with the drums, etc.)
Peace,
Tunes
