MoP Macro Library is stickied at the top of the Macros forum. Again, classes are pretty much whatever you like to play, especially if you are only using two accounts. The only thing that's changed about that since Cata is we have monks now and there's at least 1 thread on monks in the group composition forum.

There are also macros and class information in the Newbie's Guide Stickies at the top of this forum. Don't let the dates on sticky threads fool you. I try to keep mine at least up to date and we try to remove anything that is no longer relevant. The best thing you can do is read and experiment.
