I wouldn't play with rebound unless something seems wrong.  In my  
experience I find out quickly if rebound is wrong because I can't make  
fast left/right transitions (or the bike flips me up too fast).  In  
short, these problems make themselves known.  Don't change anything  
unless you are trying to solve a problem ;-)

That said, if you're stuck and still have a few sessions left in the  
day, try making one change and see how you like it.  This paid off for  
me in spades once at Infineon, and I dropped 2.8 seconds in the last  
session of the day (before the rain started)

Or come out here and do a suspension tuning class with Dave Moss.   
He'll detune the crap out of the bike and send you out there just  
holding on for dear life.  Then he'll adjust each parameter back to  
good and then way past good, one at a time.  By the end of the day  
you'll know beyond the shadow of a doubt what too soft feels like, too  
hard feels like, etc for each component.
