time aligning the transients will kill the natural drum sound and remove some depth. avoid that at all costs. the small delays between the tracks are ideal, leave them in there . the only time I would recommend make small changes (with your ear, not by site) would be when the tracking engineer just sucked at his job and created problems.
anyway, to avoid too much FT junk, I cut at the snare and move them to the grid, beat detective style, and THEN FT if necessary after glueing the tracks back together ( and cross fading the cuts). have ...fun?
