After my A&A kit went in, I'm having valve float at the higher RPMs. Decided to replace the stock LS1 springs myself, for the learning experience and because I like getting my hands dirty. Did some searches here in the forum and overall googling, and I was planning to do it according to this write-up:
http://www.ls1.com/forums/f7/how-rep...prings-132116/

Got the tool mentioned there and am planning to hold the valves up by air pressure.

This will be my first foray into the engine (if only ever so slightly into it); I've only done non-engine work so far (brakes, suspension, A/C, electrical, cosmetics,...), so I figured I'd ask for any caveats first rather than cry for help later...

Any pitfalls I need to watch out for?

It's easy, one tip is when you put the locks back on I put a little grease on it to help stick to my hand and the valve. Some use a pen magnet and do it that way.
