In general, more is better --  more rods, deeper, wider spacing, but all tied together.

It won't hurt a thing.

Note that ground rods primarily enhance SAFETY ground, not antenna performance.  Of course, if you are end loading an antenna against ground, 
anything you do to reduce the impedance to ground at the transmitting frequency will increase antenna current, which will help RF performance.
