Beyond all the CST related warm ups and cool downs that Scott Hagnas pulls from... There's the Parisi Warm Up that Martin Rooney uses that's pretty good... Also many of the BJJ/Submission grappling warm ups/ground movement stuff can be excellent for either warming up, or cooling down, depending on what you're working on that day...
Yoga poses are also an excellent cool down tool...
