Pretty simple task.. If you dont have a Clymers Manual by now, you should go pick one up, especially if this is ur first rebuild and first banshee. First, you should try and find out why it locked up on you so it doesnt happen again. If it was a lean condition, make sure when your rebuild is done you get it tuned in properly.
There's really no tricks to a rebuild. Just once you get everything back together, make sure everything is tightened down good. Torque numbers can be found in a clymers manual. I would reccommend buying your wiseco pistons, rings, cir clips, wrist pins, and bearings from www.rockymountainatv.com. Very cheap prices. You can also get your gaskets there. When you take it in to get the bore/hone job, make sure you take your pistons with you. Also, if you have a coolhead, you should prolly order another O-ring kit too.
EDIT: I just saw ur reply back.. Make sure you flush everything out that went down into the crank.
