The method used for rooting shouldn't cause any problems with your phone since it only touches a couple files. I doubt that rooting your phone caused GApps to stop working, I'm guessing that either a root file got deleted or another app is incompatible and causing problems.
You're asking how to return your phone to stock and you're correct in that it will "restore" your device, but in doing so it will completely wipe your device and you will lose everything. It will essentially return your phone to the state of when you first pulled it out of the box. This question has been asked and answered a few times and you could probably find the answer by searching, but I'll post the answer here too. For the i537 below are the only known ways to get stock firmware back on your phone:

Other than that I don't really know what else you can do.
