Nici,
some of the messages you will hear over and over on these boards is that we love the person and hate the disease... and that our recovery can NOT be contingent upon anyone else's recovery. The best way you can help your dad is to support him and love him. Since he's asked for help, you can assist in finding him a program, but after that he has to do it by himself and for himself with the help of other people IN his program.
Try to read all you can read, there are lots of good references with "sticky notes" on them at the top of the forum. Also, there are a lot of really good books that can help you in your recovery. Try to find an al anon group. I can honestly say that going to al anon saved MY life and has given me a more beautiful life than I ever thought possible.
