For one thing:
A beginner's forum would be the Tutor mailing list:
http://mail.python.org/mailman/listinfo/tutor

A good reference I would recommend for the type of stuff you are asking
about:
Core Python Programming by Wesley Chun.

When to use self:

Do you want the method to be called in the following way:
object.method()

where the method is always called by an instance of the object?

Or would you like to be able to call it like this:

method()

without having to necessarily have an object to use that method?

if the former, use "self". If the latter, don't use "self".

Hope this answers some of your questions. Join the Tutor list and ask some
more. You will get some good answers.
