If you're doing it legit, you'd be better off buying the lower level necessities in bulk from AH and then chain-task whatever else you want to make with mac Profession XP. You will need to unlock as many slots as you can.
If you're into making gear for AD, do a profession and stick with shirt/pants being gemmed as they sell well on the AH but the cost to make is high for new players.
I have no clue about alchemy at the moment so I can't speak for it.
As a matter of fact, have someone read over my tips to make sure I'm not an idiot.
