there are some video tutorials available at
http://www.3dbuzz.com i haven't checked them out, so i don't know how good they are. the introduction ones (about 2 hours are free) and the others (about 7 hours) you need pay money and become a member of the site.
Once again, i havent used the tutorials so i dont know how good they are, however i have used tutorials on that site for 3d animation software and they were very good.
i hope that helps a bit
