I think what your first question boils down to is "how to I make a view 
to itself".  The answer is usually:

from repoze.bfg.url import model_url
url = model_url(context, request, request.view_name)

As far as examples about form handling, the sample apps at 
http://docs.repoze.org/bfg/#sample-applications do a good deal of this.  None 
these have any form *generation* in them (mostly because the authors aren't 
really form generation people).
