You shouldn't have trouble with that team. I am running Pali, Disc priest, Frost mage, Dest Warlock, Ele shaman.

Destro warlock has great dps as does the hunter, ele shaman not so much, like really bad compared to hunter and warlock. I have no issues healing at all with the Disc priest.

I wouldn't worry too much about gold. If you have any old characters someplace with gold on another server, you can just buy an expensive pet from AH then cage it and sell it on your new character.
