Bummer RJP, I was hoping I could help you out here, but it looks like you're mostly trying to catch up on the older stuff that's no longer available at retail, huh? I probably have some extras of what you're looking for, at least the green carded stuff, but it's all tucked away in storage at the moment. The Mrs. and I are looking to move into a new house in the next couple months, at which time I'll be able to go through all of the old boxes of extra goodies, so maybe I'll check back in with you at that time.
In the meantime, if there's anything currently out at retail that you're having a tough time tracking down, let me know, and I'll keep an eye out for it for you (and would obviously pass it along to you for retail cost if I found it).
As for me, the only current stuff I can't seem to find are the Trash Compactor 2-packs (2 of each one), a couple Ephant Mons, and two Deluxe Clonetroopers w/ Speederbike. That's it. If you come across any of those, and have "a few" extra bucks on you at the time, I'd totally appreciate you snagging them for me and we could then meet up somewhere at your convenience. I'll give you a buzz (and/or just update my trading thread here) to let you know if I get lucky and find any of these myself in the interim. Thanks!
BTW, I went to school and lived up in Santa Barbara for 8 years. I love it there!
