Help with export/import in premiere pro

Hi Everyone

I have a question about import and export in Premiere Pro CS5.

I have some 1920*1080 .mov-files shot with canon eos 500d.

What is the best import setting for premiere pro cs5?

What is the best export setting from premiere pro (to adobe encore) to dvd?

The film is going to be projected on to a big screen. How do I get the best quality for this?

I would be very very thankful for your help!
