If they want to give me a 40th anniversary present, just mix up the setlist a little bit and add a couple of old songs they haven't played in a really long time (or ever).
As it's actually the 40th birthday of the 1st album. Is there anything on there barring the 3 all-time classics, Take It Easy, Witchy Woman and Peaceful Easy Feeling that you'd like to see them perform live 
I know the band actually got together in 1971, so technically the 40th anniversary of the band should've been celebrated this year. However, I'm assuming the reason they didn't do that is because of the terrible state of the U.S. economy. They probably figured even 40th anniversary tickets would be a difficult sell in this economy. I'm not sure the economy will be much better next year, but evidently they've decided to go ahead with the celebration next year. Regardless of the technicalities surrounding how you count the anniversary, I fully expect them to bill the celebration as the 40th anniversary of the band, not the first album. And no, there really isn't anything on the first album other than the three songs you mentioned that I'd like to hear.
However, I would like to hear them do "Doolin Dalton" with the "Desperado" reprise (which they haven't done since about '79), "On the Border", "Saturday Night", "The Last Resort" or "The Sad Cafe". There are some other album tracks I have a fondness for I know they'd never play, but nonetheless I wouldn't mind hearing like "You Never Cry Like a Lover", "After the Thrill is Gone" and "Hollywood Waltz". Those are almost all ballads, so if they want to dig up something up-tempo, I think "Good Day in Hell" would be a nice choice. I don't expect more than two vintage nuggets added to the set, at best, but pretty much any of those I listed above would make me happy. And I hope they keep doing "The Best of My Love" because I somehow have never seen them perform that live.
