-Put a rag down the void where the timing chain is before you undo the cam caps. This will prevent the half moon clip from falling into the engine.
-Have a quality 1/4" drive torque wrench in inch/pounds handy for retightening the cam caps. It's important to get those spot on. Too tight/loose and you'll have problems. A 1/4" universal joint helps too.
-Get the set of three double-blade shim tools from Motion Pro. They're small and angled and work well for determining clearances.
-When you do your shims, do them one at a time. The buckets also have to go back in the exact spot they came from, and pulling them all at the same time can get confusing. A template can also help if you are compelled to yank 'em all at once.
-Get some good assembly lube as recommended in the manual. Bel-Ray makes some good stuff, and even though it has moly in it, don't worry, it won't cause your clutch to slip as you only need a light coating.
-Make sure the bike is clean before you remove the valve cover. The internals get mad when a dried dirt clod falls in the valvetrain.
-Go slow, take your time, post on the board if you run into trouble. It's really not that hard, just a bit intimidating. Once you've done it the first time, it's a snap the next.

Oh and make sure you have the correct torque wrench to tighten the cams in place.
