If you have a typical cable/dsl interface to the internet...
You will have one external-facing IP address which will be dynamic. This means that your internet service provider can change it at will...and some of them do regularly just to stop people from doing things like hosting servers on their machines. Your best bet is to use dyndns. They offer a free version at:
http://dyn.com/dns/dyndns-free/
It's been years since I set one up but it should be basically the same procedure.
1. create an account
2. choose a domain. they have lots of domain names to choose from and then you put your unique identifier at the beginning. For instance, mysticjunkee.homeftp.net may be available.
3. Configure the specialized dyndns updater in your modem or router configuration. If you don't have one (most don't) then you need to download and run a small dyndns updater software. It detects what your outward-facing IP address is and sends that information to the dyndns servers.
4. Once it's all done (and propogated - allow as long as 5 days, normally faster) then you should be able to use the address you set up plus :8080 to connect.

*whew* - now, for a shorter answer, at least to test things out, try going to whatismyip.com from the machine with Calibre running. It will tell you what your outward-facing IP address is. On your laptop, you would need to type in that address followed by ":8080" (no quotes).
