Check my uploaded pieces for the currently-available and up-to-date ThorUI pieces. Of the ones I haven't tweaked yet (I'm working on it, I swear!), faetyl did post a folder of the raw UI files - far too many of them are out of date, but they're there. I've posted in the comments to ThorUI with what UI pieces from it do and do not work.
Now that beta is over, the storm of live events is in a lull, and the tradeskill project I was working on is complete, I'll be able to spend more time on the relaunch. Most of it is ready to go, but a few windows are not behaving as intended and there's some tweaks I want to make to the group and player windows still.
