Here is a link to various types of astrophotography:

It strikes me as curious that they do not include one for photographing meteors.
While I don't claim to be an expert, I will tell you how I shoot meteor showers.
Obviously you need a camera, a tripod, and a way of taking long exposures. You definitely want to be in manual mode.
For lenses, the wider the better - to a point. I prefer a 50mm or wider lens (that's with a flim camera or a full frame digital sensor). A 28mm - or it's digital equivalent - is about as wide as I like to go. If you get too wide, the meteor trails are too small. But if you have a fisheye and are dying to try it, then go for it.
I shoot with ISO 400 speed film or I select ISO 400 on my digital camera. A faster film or ISO setting will show more stars and more meteors, but even a fairly dim meteor, magnitude 3 or 4, will show up nicely at ISO 400.
I shoot with a wide apeture. I like f2.8 or faster. The wider the apeture, the more meteors you will capture. I know you don't get the shapest image with a lens wide open, but we are talking about stars and meteors here. As long as your focus is good, you will get nice photos.
Speaking of focus, I select my lens, then focus on something bright (Jupiter is the bright "star" in the south and it works well) and then I set my focus on manual. That way the camera doesn't hunt for focus.
Exposure time depends on how wide your lens is and how much "trailing", ie, streaking, you want from your stars. With a 50mm lens on a film camera, 30 seconds is about all I want. The wider you go, the less trailing you will have for any given time. Experiment and see what you like.
My setup these days consists of my D200 and my D300. I use lenses set at 28mm (42mm film equivalent), ISO 400, f2.8, 30 second exposures. With my cameras, I can set the interval timers at one minute, fire the first one, and when the shutter closes on it, I fire the second one. That way I always have one camera recording.
The interval timer has the added benefit in that I can fire my cameras, then sit in the hot tub with my wife and watch the show while my cameras take the pictures. I find that a fully charged battery will last 90 minutes or so on interval timer.
If you have any questions, feel free to ask. I don't claim to have all the answers, but I will share what I know.
