I've been working on the WallStreets more times than I care to remember, so I know a fair amount about them.
The most common problem with those things is the power jack. They usually didn't use enough solder when they made 'em, so the joints break really easily. If I were you, I'd touch 'em all up and see if that makes a difference. As for the capacitors, I think there are only a few ceramics on that board, maybe one or two small electrolytics. I haven't seen one go bad on there yet, though.
What screen size did you get? The 14.1" displays have a tendency to become washed-out after a while (two out of seven did that to me, no fix for it), the 13.3" displays often have problems with vertical lines (usually correctable by reseating the display's cables, all of my 13" were like that), and the STN 12"ers just look bad.
I've got the Apple Service Source manual for it on a CD somewhere. If you don't have it, I could get it to you somehow...
