One thing I would like to add is: Don't go it alone. I've done the design, art, marketing etc on my own and it would be really handy to have someone else doing PR right now while I could work on the art. Oh, not to mention the negotiations with Shippers and Manufacturers!
I also had this issue with this when I released my dice game, and tried to run a Kickstarter. Really wish I had help, because all that work for one person is insanely intense. Luckily I still found a way to release my game.
