I've got a list of preffered flash sites that help me along here if you want to take a look. Flash Resources
If you realy want to get into flash I'd say picking up a book wouldn't be a half bad idea. I know that they are great to have around and usualy are written with relative skill and excellent 'real world' explanations of what you are doing or coding. I'd look at a pbulisher like Friends of ED
for some quality books. Best of luck.
