Well, I've heard about the first one, and I don't know if there's a fix. I personally haven't encountered it myself, so I can't really help you there.

For the second one, I'll direct you to the quest page. Look under the bugs section, and there might be a solution. I do, however, know there's a bug that occurs when Vilkas' Purity quest is accepted before Farkas'. Try loading an earlier save and doing the one for Farkas first.
