Well, asking questions on this site is a great place to start! If you have questions or need help there's lots of folks here willing to answer!
I would say in addition to asking here and reading threads, if you have a half priced books or other used book store near you pick up some beginner quilting books for information and inspiration. Fon's and Porter's Complete Guide to Quiltmaking is a great book to own and covers just about everything you'd want to know as a beginner. Really some of the quilting magazines have the basics of "how to quilt" right there in the midsection of the magazine. Plus you get free patterns!
Check out sites like allpeoplequilt.com, Bonnie Hunter's site quiltville.com, and quilterscache.com for free block patterns and basic information. For free.
