With all those causing problems I'd say best to pick up either someone else's addon mix (loads to choose from) or goto curse (which as of a few months ago was the most popular) and either just update the one's which need updating or start again from scratch.
I would say though that if Blizz keep on introducing the kind of changes which affect the UI like this this problem will happen with every patch and you just need to wait until the dev of that addon fixes it
The best answer I've seen was on one of the addon sites which in effect patches your addons automatically for you, can't remember which one but that is the way ahead and I know curse was looking at doing this (so already may have).
Oh and tip buddy allowed you to totally configure the tooltip you get when you mouse over someone/thing
