As for bypassing the switch, when I got mine the previous owner had done it already with the first method (splice the wires together). This does work efficiently, as it starts everytime in every gear. However, I kept getting the CEL for Neutral Safety Switch/AC Compressor. So I just went to Pick A Part yesterday to pick up a used switch, and I'm gonna hook it up and hope it fixes it (The contacts on the switch that came with my car were worn out, causeing it to only start sometimes). Hope this helps.

If the N/S switch is just out of adjustment, (and not bad), you should be able to hold the key in the start position and move the shift lever back and forth from reverse to drive.
Across the neutral position, and the starter should work.

The alarm thing may be your problem. Can you put the key in the 'on' position, and then, using a starter jump botton (buy one),jump the starter and start the car.
