There's a new gold making addon that is making the rounds called Trade Skill Master.
The developers are the same people who brought us Auction Profit Master and Scroll Master.
This addon combines all the below addons that I currently use for crafting:
Skillet - Tradeskill window
Kevtool Queue (KTQ) - for queueing up items into skillet
Lil' Sparkys Workshop - Show prices and profits of items to craft
Altoholic - keeps track of items on alts and inventory (KTQ dependancy)
Auction Profit Master - for canceling, posting and auto-mailing inventory to posting alts
Snatch from Auctioneer - to find underpriced items after scans
Here's the youtube video of part 1 - showing how you can craft with Trade Skill Master, the addon is still in beta but they seem committed to work through the bugs and I really do think it'll be the next big gold making addon:
