"bzr pull --remember" from another location will change the parent
branch. Alternatively, you can edit the parent branch
in .bzr/branch/branch.conf directly.

The repository is what stores the actual revisions. A repository can be
colocated with a branch or be higher up in the filesystem (a shared
repository). bzr-svn creates shared repositories by default unless you
specify --standalone. "bzr info" will tell you the location of the
repository that's being used by a particular branch.

The branch is mainly just a pointer to a revision in the repository.

What exactly did you find disjoint? What places did you look at ?
Hopefully we can improve this a bit. :)
