I'm sorry of that I can't help but I would be really interested in having the same infos you're looking for. I'm a newbie too, but I'm spending my spare time working on TG.
For session management you can find plenty of infos on http://www.cherrypy.org/wiki/CherryPySessions The most interesting topic is the acl framwork, AFAIK there isn't a framework in TurboGears for acl, but it would be a nice thing to have. Maybe we could start a thread to discuss the specification of such a framework... Bye
