I found it doesn't matter if I put the --excludes before the -czf or after
everything, I still end up with EVERY dot file in the directory instead of
ONLY the ones that are NOT on the list.
wooledg:/tmp/x$ touch .good .bad1 .bad2
wooledg:/tmp/x$ tar czf ../foo.tgz --exclude ./.bad1 --exclude ./.bad2 .
wooledg:/tmp/x$ tar tzvf ../foo.tgz

I think your primary problem is that you are passing absolute paths
to tar. This is evil. You wouldn't want absolute paths in your tarball,
and in fact, GNU tar will chastise you for doing so, and then will strip
the leading slashes for you. (Unix tar is not so forgiving. It will
gleefully do exactly what you said, creating a tarball with absolute
paths in it, which means it cannot safely be extracted.)
Perhaps there is some kind of collision between the auto-stripping of
the leading slashes, and your --exclude patterns which still have those
leading slashes on them.
I actually have several accounts which I want to back up but not include
all the dot files. It would be too much to go into each account and run
a script. I would like to do it from one account.
