This site and the forums here at SUN are a great resource. You could also check out the San Diego Entrepreneur Group. This link will get you to a group of young entrepreneurs who meet face to face monthly in the San Diego area. They help each other over the humps of starting out.
You could also start your own group in your area through meetup.com and easily find those who have similar questions as well as more experienced entrepreneurs who can provide answers and guidance. If you are self-funded, check out the bootstrapnetwork.com as they are also organizing area groups able to meet face to face and really work hands on to get you going. Hope this info helps and good luck!
