As silly as it may sound, there is no reason to really worry about some difficult terrain! As the Skipping Shoanti, I should know.
1) There is no limit per round to the number of jump checks.
2) By making long jumps over level terrain, you will never fall far enough to take damage and thus, never have to worry about falling prone.
3) With no running start, a result of 2 moves you 1 foot.
Just for giggles:
A) Outside of combat you can just take 10 and skip your merry way everywhere!
B) Just remember high AC and Acrobatics rogues, it may be easier to jump over an enemy than trying to tumble through it's square...
