hey photoresistor, the compression depends on the players style. when I track myself, I generally use a very low ratio 1.2 or less, slow attack and fast release and low threshold maybe around -30db. but for instance with my son, he plays the cymbals a lot harder, so I use an exciter to tame the cymbals (very fast attack and release) to bring up the drum hits (threshold balances Drum to Cymbal), followed with a general compression similar to above. I set the exciter to bring up the drums and get out of the way of the cymbals and the compressor is a leveler. each song usually requires a different approach. two plugin compressors I use a lot are the PSP Vintage Warmer and Waves RCOMP. I usually only use the Vintage Warmer on the whole kit mix and on the Kick.
