FSP, WOD and... What else?

I'm new to WOD. I've tried to read up but have a question. I'm following a program of:

M-T-W-F

wrist warm up

HS work - 10 min (5 days/wk)

FSP

WOD

My question is should other work be fitted in? Like legs or work on certian movements (such as XR press shoulder stand, from the WOD 3/25/11)? Or should work on "new" (to me) movements be done when they come up? Thanks

What else is flexibility and joint prehab as well as skill work which would be stuff like dive rolls, cartwheels, roundoffs, front/back handsprings for a gymnast, but might be arm bars, submissions, standing and ground work and such for a grappler.
