kick on the first beat (1.1) (and then sometimes again 1/8th beat before the 2nd snare (between 1.3 and 1.4), sometimes 1/8th before next bar usually at the end of a phrase, sometimes you get a double kick at the start of a bar - other variations too of course)
snare generally @ 1.2 and 1.4, it varies though, I use ~4 different snare patterns, the snare @ 1.4 is probably the most consistent hit - snare rolls vary, but they tend to be around 1.3 give or take 1/8th-1/16th
general structure is 8-16bar phrases, in 65bar sections
most percussion is 1/4-1/8th, fast hats and toms/etc @ 1/16th, very rarely @ 1/32
all of the above is based on 4/4 time, there are other time signatures that pop up including 3/2, half time and more
