Okay how can I cap a velocity? I know the velocity and I know the angle travelled. I can take the magnitude to determine if the length of the velocity vector is to high but from that point I'm not sure how to cap it without corrupting the vectors direction.

pseudocode:

if(|v| > maxvel)   v *= maxvel / |v|

Of course you shouldn't take the square root until it is necessary to do so, so have the |v| and maxvel squared in the if statement, then take the square root if it's true.
