I agree with the above advice. Also you can go to YouTube and just search for whatever thing you're having trouble with. Asperger's is pretty varied, so some people have non-expressive faces, others have a habit of not looking at others while they're thinking, speaking, or listening, other people have a distinctive walk, and then it's really common to monolog while talking about things that are interesting to you and to feel maddeningly bored when someone else talks about something you don't care about. Most people with AS have their own blend of things that have developed over time. I think it's important to remember that ALL social behaviors (for people on the spectrum and for NTs) are learned, just like when you were little you learned your native language. All you're doing is picking up a few phrases in a foreign language so you can better communicate with others.
And yes, depending on what area you live in, you might be able to find an IRL class to help with social skills. I would start with YouTube, though, because that's free. You can also let us know what kind of social skills are harder for you and people should have some more specific suggestions. There are lots of threads on here already that may help as well.
