I've been reading around about AP, and I'm still very confused, because I think some of the things I'm reading are to do with the "old" AP and some to do with the "new" AP, so it's made me quite unsure what is actually possible with the new AP
so a simple question really, can I download all post-SP2 updates (even though I have a lot already installed on my comp) and either A) slipstream them into a Windows install (nLite for example) or

if that's not possible, make an "update" disc (iso) to just run on the computer after a Windows install?
if either of these are possible could someone give me just a simple overview of how?
any help appreciated,
cheers
