What curriculum are you using in your class?
I would try to find more ways to practice live (with classmates) or with free resources online. There's no need to spend lots of money on books and DVD's at this stage.
Once you get down the basics, I encourage you to seek out Deaf events that you can attend.
In the meantime, study as much as you can about Deaf culture so when you do meet Deaf people you won't make the usual hearing person social gaffes.
Is your instructor hearing or deaf?
