For the front you might want to try XR80 or forks. I installed a set on my son's bike and it gave it at least another 2-3 inches of travel (more if you have a longer rear shock. Pics are here:

As for the rear we had a Prowheel shock and my 9 year old broke it. The shaft broke and the shock came through the seat. I would not recommend it for jumping. We ended up getting a shock extender on ebay and a bbr spring for the stock shock. We also have a I-shock on our KLX110 that is very nice ($320) and it comes with 3-4 different springs.
Good Luck . . .
