+1 on get yourself a copy of Ivan Law's book Gearcutting. It's one of the Workshop Practice series and costs about $14 delivered to your door. It has everything in it you need to know.
There are also online calculators that you can use to find out the centre distance of various size pairs of gears in various modules. I dont have a link to one but have used them in the past. Law's book also has charts and calulations for centre distance vs module vs number of teeth etc.

If at all possible you should make the cam- crank center distance such that gears of a standard pitch will work. If your center distance does not allow use of a standard pitch Ivan Law's book contains info that lets you make a cutter for any pitch.
