My question is: I don't know any Python and would like to start learning it. Should I bypass Python2 altogether and start with Python3 or stick with Python2?

You should definitely learn Python 2. Almost all libraries still are on 2, so if you tried to go straight to 3, you'd have to struggle your way around most newbie documentation on the internet - Especially if you're planning on doing Django work.

Anyway, there isn't a whole lot of difference between python 2 and 3, really. The "proper" way of coding in python2 is very similar to python3.

I wish this weren't true. We all need to be pushing towards 3, and I think introducing people to 2 isn't helping the community in general -- but it is the right thing on an individual level.

If you would like to use App Engine (great & free!), then stick with Python 2.5 for now.

Or pretty much any other major Python library or framework - Django or Twisted, for instance.
