Thanks for the confirmation that I should do the analog boards too. I've heard of "Macintosh Repair & Upgrade Secrets" - while Alibris has somone selling a new copy for $96.11, Amazon has a seller with a new copy for the low, low price of just $1,188.39. Wow. (I ordered a used copy for $20.)

My non-surface mount soldering skills should be pretty good (many years ago in high school I took a summer course in electronics that involved a lot of soldering, both practice on junk electronics and a couple of kit projects). It's the surface mount stuff that I'll have to take extra care with.
