skinning and Leatherworking. Maybe Engineering/Mining if you want to create your own ammo. Depends on whether you want to have money or you like working a profession better?

Skinning and Herbalism or mining for money - enchanting and tailoring for fun

It depends on what you want to do, what your racial bonuses are, and what class you are playing. Engineering is dependent partially on faction affiliation as well.

Gnomish engineering provides some benefits not available to those affiliated with the Horde, such as transportation to an Alliance village in Blade's Edge Mountains.

Enchanting and Tailoring are both stand alone professions, their base materials not gained from any of the other professions.
