Hi Jen. I have 9 of those drives and have been an active member of the OCZ forums for quite some time now and can honestly tell you that there is little to be concerned about with these types of utilities.
But what happens after the drive reaches 0% though, right? Well.. the counter will reset to 100% and life goes on just the same.
However, I will tell you that the newer firmware versions will actually have lower write amplification and can help the smart data to become more accurate. Not that it really matters since even with the later firmwares.. the conter will still reset to 100% when it hits 0% once more. I have even seen some members drives go to 3 times the actual PE/c ratings for these drives(upwards of 15k) and still maintain fresh speeds similar to new.
So, I would recommend going to the forums and updating the firmware to the latest. Backup your data just as a precaution, but since it's non-destructive you should be fine. Hope that helps reduce the concerns and lets you keep the drive alive that much longer. Good luck with it
