I have only 1 public ip, although I have 2 applications on port 443 that need to be usable externally.  Is there something else I can do to get them both natted to the outside?

A reverse proxy comes to mind.

NAT is happening at the IP and TCP layers, so you either need another IP address or you need to move one of your TCP/443 apps to a different port. It probably isn't feasible to move the app to a different port (assuming its public facing), so a 2nd IP address is probably your easiest and/or cheapest option.

That said, Rich is right on with his suggestion of a reverse proxy. I use F5 Big-IP's in this setup and let the URI's of the various web apps dictate how I will forward traffic to the servers being proxied. Here's a doc from F5 that gives an intro to URI translation (http://goo.gl/zyWGWN) and how the Big-IP proxies traffic. Don't get lost in the details, it's really just to show you what conceptually what's happening. And don't think you need an F5 solution to get a reverse proxy for web traffic. The Big-IP is an enterprise solution that handles much more than reverse proxying. Apache, Nginx, and Squid are all software proxies you can load onto a Linux server.

The Q&D: 443 traffic comes in from the Internet, the firewall NAT's to an address on the reverse proxy, the reverse proxy examines the URI and forwards to some web server.
