Welcome to the club! :)  If you are coming from Solaris Zones it won't take you much time to feel at home with FreeBSD Jails.

If you are a newcomer to FreeBSD, I suggest you to use a -RELEASE or errata branch. -CURRENT is for developers and "hardcore" users.

To make a so-called "service jail" actually seems the way to get what you are looking for, but I think you will feel much better by using a full jail management framework such ezjail (http://www.FreeBSD.org/cgi/url.cgi?ports/sysutils/ezjail/pkg-descr).  It will definitely help you to get a working environment in minutes, enabling you to manage it with a more "Zones-like" approach.
This tool is also interesting because it makes all jails use a single read-only userland, thus keeping both disk space consumption and administrative efforts low.

That's the easy way, just to make you "feel the power" without spend too much time... but I strongly suggest you to make your hands dirty by following the "official way" to build jails, to really understand how this great OS partitioning system works!  The better source is obviously the Handbook (http://www.freebsd.org/handbook/jails.html).
When I was a newcomer to jails, I wrote something about my first experiences, maybe it might be agreeable to have a look at it:

Hoping that these little suggestions will be somewhat useful to you.

Sincerely.

Andrew
