Sounds like you've pretty much got it covered Chief! SSH is useful for a
lot of things, but if you don't want it, don't bother. Whatever firewall
manager you choose is up to you - anything will do, it's going to be
talking to iptables at the backend no matter what. Upgrade to keepass2
simply by starting it, and going File > Import and choosing your old
keepass file (I think it's an .idbx file, or something like that) to
pull in all your old entries. Lastly, if you do choose to encrypt home,
which is probably a good idea, you will get a dialogue at some point
telling you it's generated a key header file that you should record and
save somewhere safe: it's really *not* joking about this. If your
encrypted home is ever corrupted or the password lost (and there has
been a nasty ext4 bug recently) you will need that header backup to
recover your partition. Of course, if you're maintaining good and
constant backups, you can recover from there but thought I should
mention it.

Good luck!
