Sound advice, young god.
I'd have to listen to the songs more, but just thinking about the titles, When I'm Over You and I'm Movin' On seem appropriate.
The fast songs, the rockers would generally be a good bet. Do you have Cut Me And I Bleed or any similar collection? As Ron said, the laughing version of Are You Lonesome Tonight--boy, it's hard not to at least smile when you hear that. Laughter is of course the best medicine. I'll have to scan through my CDs later and so if I see some other specific things to recommend, I'll let you know.
Movies...If you want to watch an Elvis movie, I'd shoot for Follow That Dream, but I don't have to tell you that. Have you seen Matchstick Men yet? It just came out on video in the last week or two, and I'd definitely recommend that. It has lots of funny moments, although hopefully nothing too stitch-busting, and it's got plenty more to offer too.
I hope that helps, and I may have to recommend more to you later.
