Lab printing

When processing images in photoshop that are to be taken off to the lab to be printed - what print settings would I use? I'm talking about your average high street lab (for printing holiday snaps) where unfortunately it has been my experience that the staff don't know too much about what they are actually doing.

•In photoshop print settings under "colour management" do I choose document or proof? I would think "document" as I'm not printing a proof. If I was to use "proof" though what profile do I choose as surely "working cmyk" is only for newpaper? Or would you use it for other forms of print like printing a high quality sunset landscape.

•Would I let photoshop determine the colours, the printer or no colour management.

I hope this makes sense, thank you

Here is a page full of tips that is written for this companies printer profiles, but I think can be generalized for other printing situations:

Helpful thanks but I've read a few of these articles on the web. While they do clear things up I was actually after a couple of answers to my specific questions above which these articles on the web can't answer.

I usually chose "document" and just use proof if I need the image to look like it should on the intended media (newpaper, photo, toilet paper...)
