My first advice to anyone getting started in animation is buy a copy of The Animation Book by Kit Laybourne, Crown Publishers. It has worlds of information on how to make your own animation on paper or in the computer.
My next advice is to join the local branch of ASIFA for the great information they have on all types of animation and animation careers. The San Francisco / Bay Area ASIFA-San Francisco is particularly active; you need not live in the area to join. Become a member and get their monthly publications and emails.
