The "branches" directory is really just a convention. It's a
suggested place to put copies made for branching purposes. If you
were doing testing branches and release branches, it might make more
sense to have "testing" and "releases" instead of a single "branches"
directory. It may be a little confusing initially if you're used to
the CVS-way, but it really is a powerful way of doing things.
Also, nothing "goes away" if you don't have a branches directory.
You're still able to make cheap copies from any location to any other
location. You're also free to create a branches directory at any
point in time, not just when you create the directory.

See above. The features are always there, even if you don't have
directories named /branches and /tags. There's also nothing magical
about those directories, they're just conventions.

If you'll excuse a bit of self-promotion, you might want to take a
look at my book "Subversion Version Control". I discuss "the
Subversion way" in great depth, as well as ways you can integrate
Subversion into different development styles.
Here's a link: http://www.phptr.com/title/0131855182
It was released under the Open Publication License, so you can
download a pdf of the book if you'd like.
Of course, if you like if feel free to buy a hardcopy ;-)

Yes, you're exactly right. The contents of the directory trunk will
be checked out into a local working copy directory named project. If
you omit the word project, then you'll check out the directory trunk
with a local working copy name of trunk.
