Hip and valley timber framing is an ambitious way to start. It can get a little tricky. This is from the Guild website: http://www.tfguild.org/downloads/publications/HV-III.pdf.

On your doorway, sure that could work. What's the scale of that bump out? If you don't want posts, the easiest solution may to just run common rafters (with the ridge line perpendicular to door), and then hips off of that.
