THE FIRST THING TO KNOW IS THAT WATER OR MOISTURE IS AN (ELECTRICAL) PATH TO GROUND SOUNDS LIKE MOISTURE IS GETTING IN THE LOCKING SYSTEM AND RELAY YOU HAVE TO FIND WHERE IT IS GETTING IN (MOISTURE) AND CHECK THE FUEL-PUMP RELAY THE SIMPLE THING UNTILL YOU ABSOLUTELY KNOW WHERE MOISTURE IS TO REMOVE THE FUEL PUMP RELAY SO THAT THE BATTERY WONT GO DEAD

Try cleaning out the small holes between your rocker panels and the sub-structure. They can be barely perceptible, but if you look carefully under the car, they are actually little channels that direct the water flow out of the car that leaks on during heavy rains. Use a coat hanger or other wire to re-open them and let the water out. If not, the floor will continue to get wet until the rockers rust out. Other causes may be seal leaks behind the glass, or trunk seal leaks especially in sedans.
No, but water on your distributor or plug wires can. If you're missing weather seals or splash guards you could be getting water in the engine compartment and that COULD be your problem. Wet wires cross-firing will often keep cross-firing after they dry out. It could also be a timing issue or other problem unrelated to the rain.
I'm sure the car has seen heavy rain before without causing any problems. Did rain get inside the car or the car driven through high water? Check the fuse panel for evidence of water contamination. Look for burned fuses or corrosion. If you can't find any fuses or relays that got wet, then I would look to the ignitionswitch.
that buzzing noise you hear is likely one or more of the relays chattering. basically you will have to replace all the ones that got wet inside. locate the fuse panel under the dash and the one in the engine compartment. put your finger on each one to located the one that is stuck. replace that one first. incidentally you can use wd-40 (penatrating oil) to get rid of the moisture as it doesn't conduct electricity.
Sounds like you need new wires and or cap and rotor, had the same problem on my jetta 1.8L when I would drive it in heavy rain it would bog down and misfire. The water blows threw the rad right onto your distributor and wires causing the short (old and cracked or just defective). Try it out I'm sure that will fix it.
