Cconsider also looking at Pyramid Web Framework. Provides nicer defaults and does not rely on threadlocals and globals. By defualt you will also get sqlalchemy and jinja2 templating out-of-the-box. It also handles building REST apps nicely.
Django on other hand will give you monolithic solution for the price of less flexibility than flask/pyramid.
If you just want to handle REST views - I think falcon framework is nice (speed wise) - haven't used it myself yet though.
You mean like auto-generated admin panel? I would look for something directly related with sqlalchemy - not pyramid. I don't use such panels so I can't give good advice here.
