Hey man I plan to take this up too so ...

Thus far I've seen tricking sites have good breakdancing tutorials.
Gymnastics sites are good for Flips and stuff that add flare.
Dynamic flexability will help in the long run so some streching articles are easy to find on the net.
And youtube is always a good resource so give thoese a try.

Here is a vid I found for some moves give it a look.

For more just look in the related videos section (Right hand column)

So anyways hope this post helped, if I find any more usefull resources I'll let you know.
