If you want to make it easy just get a switch that will spray when you press the gas pedel all the way down.

this will tell you how to wire everything...also get a fuel pressure safety switch

Ick. The Zex kit's nitrous controller connects to the throttle position sensor, and will activate at WOT... so there's your WOT switch. The newer Zex kits also watch the fuel pressure, and when it gets too low, it stops spraying. This may be for the kits for the 05+ only... it's out there, but don't plan on that being included.

You don't -need- the gauges, bottle warmer, or window switch, but they all do help. The window switch is probably the most important one of the three optional things... I am just very careful when I do spray (which is rarely anyway). I spray after 3200 RPM or so, and stop at 4800. Small range, but I have a large margin on either side in case something does decide to go wrong. Most importantly I do not powershift when I am spraying... that's asking for trouble.

Bottle warmer and gauges are a "nice extra." The bottle warmer, like has been said, will keep the bottle warm so the pressure is at high enough levels. With the wet kit though, if you have too low of nitrous pressure, you are only going to go rich, which is not dangerous for a short period of time. I'd rather have low nitrous pressure instead of low fuel pressure. You could get a nitrous pressure gauge, and maybe a fuel pressure gauge... you shouldn't need them though.

I am running a 75 shot, timing did not need to be backed off, and I have not moved my plugs down a heat range (EDIT: I did not need to close up my gap either. No signs of missing at all when spraying, just get the good feeling of a nice hit of extra power). I do check them after I spray, and they look fine so far. If they start looking bad or for some strange reason I start pinging/detonating (doesn't happen now), I will move down a heat range. I last sprayed only like two weeks after I got my nitrous kit in, so it's been 3-4 months since I sprayed.

Edit again: As long as you are safe with the kit, you will need nothing extra. Just be aware that if you just sprayed, either drive around for a while to let any pooled fuel in the intake evaporate and get spent, if you do turn the car off within a short time of spraying, do not try to start it again for a few hours to be safe, maybe more. Protect your wimpy plastic intake!

If you already have the catback and midpipe, I would go ahead and get the headers just to finish off the exhaust. And then you can get the nitrous down the road.
