Corey - take a look at www.theknot.com they have a page of what to look for and questions to ask for just about every wedding item. Martha Stewart www.marthastewart.com also has some good information.
As far as prices go it all depends on how many pictures you want, what sizes etc. Hope this helps.
You might want to consider asking who will do the actual developing of the film shot at your wedding. You want to make sure the integrity of the photo is kept through the developing process.
Also, some places will do an engagement photo for you as part of the package. I think this is a great idea. It gives everyone the opportunity to get to know each other, plus you get a formal shot and will have a better idea of the whole situation before the big day!
Corey,
