This guy has a pretty good write-up on the disk swap, here
if you go that route. If you want to stay with drums, there's a good argument for that here
as well as some maintence tips from this dude in Kittredge...
My vote is stick with drums- you like driving the 40 more than you like working n it, and the right amount whiskey & good beer should net you a good amount parts & tech advice. I gave you back your jack stands, right?
edit: Oh sure, post while I'm posting..
