The battery terminal switch with key will delete your radio station settings and delete any stored codes. You can save the radio stuff with a 9v. battery that plugs into the cig lighter but I don't think that will save the codes.

I've had 3 no start problems with VATS in 5 years but you only have to wait 10-15 minutes and the VAST times will reset, always started afterwards.

I have an aftermarket alarm but put it in only because it came with the remote door locks (which '92's didn't have).
