Slipstream Secrets

[Okasional]

I'll bet I've read fifty articles on Google dealing with slipstreaming, as well as the excellent Sticky on this forum, and I must be blind because I can't find any discussion of these questions:

1. I have a Toshiba OEM CD that installs XP Home, an XP Pro upgrade disk, and a SP2 CD. Do I want to integrate SP2 with the OEM disk or the upgrade disk? (I assume the latter, but I'd like to be sure.) And after that, to re-install do I first install the OEM disk, then the slipstreamed upgrade?

2. Can the SP2 CD be used directly to slipstream, or do I have to do the loooong download to get what the Sticky refers to as a "Network Install" version? I can't see any files on the CD to transfer to my hard drive, even with hidden and system files showing.
