Haven't changed my UI in years...please help!

I realize that I'm probably going to be repeating things that have been asked before, and if I had more experience with this sort of stuff I'd just try using info in other threads...

Can y'all show me where I can get some add-ons that are 2.4 compatible for my Mac? Here are the sorts of things I'd like to get:
1) Auctioneer
2) Some sort of mod that helps with my engineer mote farming, showing me where I've found motes before and helping me design a path
3) Anything to help me tank =P

1.) http://auctioneeraddon.com/
2.) I'd suggest "Gatherer" together with "Routes". Both available here:

3.) Help in what way?

Nah, there's plenty of mods for healers and DPS, but about the only thing you could do as a pally tank is get Tankadin and flash like crazy when RF is off. You actually need to be able to play to be a tank.
