EDIT: Nevermind, I was talking about nLite (
http://nuhi.msfn.org/index.html)
I've used it for my current XP install and it's been really great, way tight and stable. It actually makes things alot simpler, as it'll ask you all the usual XP install question, and integrates any service pack and updates you provide it into a single ISO. Installation time is thus shorter, post-install tweaking is alot shorter (no need to turn off half the services and half the settings etc.) And it makes the Windows dir alot smaller too, mine is currently sitting at around 850 megs for a full install with all drivers, sp1, tons of codecs, security updates etc (this includes hand-removing dllcache tho I guess, I don't think nLite does this (or it might by this time, I don't know)). Probably won't matter much in these days of 400gb harddrives, but I like to keep things clean and tidy myself, so I think it's great.
About not being sure about what to remove, as far as I know, if XP needs something that's not installed, it'll prompt you for the XP CD to install it, so you can just feed it your normal XP CD if it doesn't find what it needs on the nLite one.
Here's a list of the components I removed, note that I don't use wireless, printer or filesharing:
