Not really a list, but anyhow ...
So after getting lucky on a few drops and rolls today, I decided to give soloing Stonecore normal on my paladin tank a shot. It's a fairly short run (around 10 minutes) to down the second boss, so not a big time-investment by any means. Regardless, with MoP around the corner I think I'm going to postpone farming him until level 90, where it should take even less time, provided there's no changes on drop-rates or something like that. Ditto for VP.
Having been absent for most of Cata means I have not had a real shot at the raid mounts either, so that's going directly to my to-do list come MoP. I was shocked when they didn't remove the achievement mounts in Ulduar, something they did with Naxx for instance, and at the time I wasn't too happy about the idea. Moving forward, however, I think it was a great idea. ICC HC and Ulduar runs are still popular on my server, and I imagine they will soon be joined by Cata's raids which does give something more to do I guess. Sadly, at least IMO, many of these runs are held by people to get their alts mounts, and that, for sure will be gone soon.
So MoP to-do list:
Solo VP and Stonecore.
Run all raids which I've missed this expansion.
Complete Glory of the Cataclysm dungeon master.
And decide whether I want to get back to raiding.
