Best keyboard/mouse for gaming on an Apple?

I’m looking for a keyboard/mouse combo for my iMac. I currently use a slightly ergonomic Microsoft set that uses a wireless USB dongle. I would prefer a bluetooth, with quieter keys, also with the mini ergonomic “kink” in it, that has some additional programmable keys on the keyboard and possibly additional buttons on the mouse that I can use to map commands in World of Warcraft.

For price, I’m looking to spend between $70 and $100, though I’m willing to spend up to $130 if it has some extra whiz-bang features that warran the expense. Any ideas?
