If you buy a domain you choose the name you want.
The name will start always with www dot ...
You need to find a host, if you use them, I'm not sure about transferring the details.
It's easy to let people NOT to type www as ALL websites are http:// (or https:// - but that is another story).
So on your card you would put
http://whatever.tripod.com
Does that help?
This is for the FREE sites on tripod.
