Re: writing backwards?
Actually, he may not have anything at all. I see kids all the time that write backwards, it is just a prewriting skill. A lot of kids do this, and turn themselves around, some need help learning that we write from left to right.
You might help him out by writing her name down for him, or pointing to each letter as you write it for him. When you read to him, use your finger from left to right and point to each word as you read it.
Give him time. It does seem strange, actually I just marvel in the fact that kids can do this! lol lol
