I purchased a fob on ebay as well for daughter's '95 Buick. It arrived with a Pontiac logo, so they must be fairly interchangeable. The instructions for programming the fob were to jump positions 4 and 8 on the connection where the ODB scanners connect. The method for yours may be different and the seller should provide the directions. Beats going to the dealer.

As for the leak, I can't help.

The vents will probably have to come from a junk yard as it's a royal pain to find interior trim parts, and even more difficult to translate their definition to a layman's term may be.
