Well, for me, and I am a late deafened adult and still trying to learn ASL and will start classes in January, I get videos from the library and a website, have books, use the net with various sites that I will include at the end and I am a member of the local deaf club. I will be going to deaf socials and they already know that I am a newbie with ASL and are willing to work with me. None of them speak or read lips so I get to write a lot of notes but they don't mind. They are willing to help teach.
You might check to see if there is a Deaf Service Center or something like that. Check with your local library for any local services for the deaf community.
The websites are as follows:
• ASL • American Sign Language
ASLPro.com Home
DCMP.org :: Home
Hope this helps.
