No.  Pushing works between repositories.  It is the way to propagate
changes to others.

No.  Saving a file will not give you all the version control history and
tools and diffs and branching and other tools that committing does under
git.  You have all that working machinery to your disposal once you have
committed.  Pushing just pushes out your commits (and not just a
snapshot) to the remote repository.  It does not change what you are
working with.  Your own repository and workflow is not affected.  You
never need to push in order to get something into better working order
for yourself.

Note that while you have not pushed out anything, git has a variety of
tools for rewriting and cleaning up your own branches/repository.  In
that manner, a new feature usually arrives in one coherent series of
commits.  Also, if you are developing a new feature, you need not push
it out to the central repository, but can still share the development
with a private set of other people.

Pushing will, yes.  The act of pushing will make the remote trunk assume
the state of the current trunk (without dropping changes only available
in the remote trunk: in that case, git requires you to pull and merge
those first).
