I know this is the Nikon forum but I think its still relevent.
There is like a 16 part guide on how to use the Canon EOS 350D, although a lot is done with the 350D in mind, there are still some parts which are relevent - but the audio goes a little out of sync!

You can find the rest of the parts from there.
Not Nikon but I hope it helps.
Hoya or Jessops UV filters should do, and it depends on the thread size at the end of your lens, e.g. 52mm, 58mm, 72mm etc.
I to am planning to get a 50mm F/1.8 lens, depending on the thread size, I think 58mm, then a 58mm Hoya or Jessops UV will do just fine.
UV filters as far as I know as simply used to protect the front element of the lens from getting dusty, scratched etc. when in use.
