I've been thinking of having prints made of some of my Vue 7 scenes, and I was wondering; are there any specific settings I should be using in Vue to optimize them for printing? I'm planning on 11 by 14 inch prints, and using a photo printing service. 

Also, I was planning on using Wal-Mart's photo service.  Should I consider using a more expensive service, or all they pretty much all the same?
