Ok, but learn how to build debs from the debian sources, and it will
come in handy. Remember you will first need to fetch the build
dependencies for the package you are trying to build.

Right. Though you could probably compile sid sources on woody, at
least for a while (this the divergence becomes great).

Actually, I think downgrading is not officially supported.

Use the grep-dctrl package. Example, to see all packages with priority
required do 

grep-available -Fpriority required -sPackage | less

and you get a list of packages you don't want to mess with. Never try
to upgrade these packages to the unstable version if you are running
testing. You might also want to back off packages with priority

See http://www.debian.org/doc/debian-policy/ch-archive.html#s2.2 for
more information about Priorities.

Looks like that. I'd now change it to something like what I have,
though. You don't need to pin testing if you are running testing by

Yes, I don't think there is much else you can do at this point. If you
run into serious problems later you will just have to reinstall.
