1) I don't use dessicant, although it is not a bad idea, especially if you are messing with your camera in an A/C room and then running out into the hot humid tropics and jumping into the ocean. It will keep things from fogging up.

Ike housings typically have plenty of room and you can stuff tampons in there to absorb minor leaks, too.
2) Well, it depends. Why do you feel you need to set your ISO at 200? Was this evaluative process done on non-flash results or on your u/w strobe assisted results? If the latter, was it the flash exposed areas or the background?
If you were using 400 at 400 and using guide numbers for 400 and the flash was not strong enough, just use the 200 guide numbers without changing the film speed. If you are trying to brighten the background, then keep your strobes set at the 400 guide numbers.
3) The technical answer is that EV and TTL metering are separate evaluative functions. In practicality, one does affect the other, especially when using flash as primary light as opposed to fill. Using EV as a primary adjustment worked best when I was shooting digital with manual exposure and manual strobe power. For film and aperture priority and TTL, just stop down and you get the same effect.
