bzr uncommit -r <revisionspec>

that leaves the changes in the working directory, though. You can use
"bzr revert" to remove the changes from the working directory.

"bzr push --overwrite", but please don't use it. It's the same for
git, really. Once you've pushed it somewhere, don't remove stuff from
it, or rebase it or whatever. If anyone has pulled from it and based
work on it, it's extremely awkward if they want to sync up with you.

bzr merge -c <revisionspec>, but its use is discouraged.

No.

bzr tags

I still don't see how any of the above are *required* to start working, though.

"bzr <subcommand> -h" shows the help for the subcommand.

"bzr help <foo>" is roughly the same, but it provides help for a bunch
of things other than commands.

"bzr help commands" shows you (almost) all the available commands (bzr
help hidden-commands shows a few extra commands that most people will
never need)

"bzr help topics" shows a bunch of topics that has more extensive explanations.
