Does the DSL Modem or your firewall get assigned the external IP?

Depends on which one of the above two get the external IP.

Not really necessary provided your firewall gets the external IP your
looking for.  If it does, you can use a dynamic dns updater like
ddclient, ez-ipupdate, or ipcheck to update your IP with an external DNS

AFAIK, as secure as your SSH tunnel.  It tends to be slow, forwarding
VNC over an SSH tunnel is normally faster.
