Artie, sorry if I did not quote you - I thought it was obvious about the PRAM.
AFAIK, reinstalling SL goes by A&I by default. Since the SL install disk was 10.6 (over 10.6.2), it left the machine with 10.6. It did not restart after the process, but did not ask for anything during it. I then applied a pre-downloaded 10.6.2 combo update, then launched Software Update, and applied all updates from SU, except for the Security 1-2010. So far, so good.
P.S. The lucky kid saved me a bunch of money getting through college in three years instead of four, so I guess that MBP was well deserved!
