As far as the video out goes, there are a few apps that can acomplish this in theory, though i've never tried them:

this will let you see your screen remotly and control the phone. Not intended for video calling on the phone, but you can remotly contact the phone, use vid, see the screen.
If you're looking for a webcam type application, i suggest trying this:

this will let it connect via bluetooth or wifi and act as a web cam.
Just my 2 cents, havn't tried either app
