Help me secure my Debian server

I've got a virtual mail/web server that I rented up and running and I want to put a Firewall on it.
The problem is that I've only got access to it through SSH, plus I'm not at all experienced with dealing with firewalls under Linux.
Does anyone know how I can install a Firewall or something similar while maintaining access via SSH (so I don't install it and poof, TCP Port 22 is closed)?
