Hi, Mac+Pc user looking for some advice

Here is my situation, I have a macBook Pro running synergy to my PC. I play on the Mac. Right now I'm just going to do 2 characters. I have a 70 shadow priest with epic gear, and a 70 warrior with decent tank/dps gear. Does this make a good combo? I want to do some farming for now, probably the PreBC 5 mans. Should I have the warrior tank or dps? I'm probably going to play the spriest because he requires the most attention and can put out much more dps.

Should I just clone keys that I press on my mac to send to the PC? Like cast MindBlast, which links to mortal strike on the warrior?

Or maybe I should level a healer, and use that with my spriest?

My friend has a 70 shaman who could heal, and he doesnt play anymore, but its under his name and I hear that this would be a bad idea. I don't want to get banned.

Thanks
Jeff
