<p>I am ready to start using SVN, but I have NO (as in the money required for free beer) experience with source control.  I have installed subversion on my server (that was easy, 'apt-get install subversion') but now I don't know what to do, how to configure it, or how to use it.<br /><br />What suggestions do you have, and where can I find good resources to learn to start using it?<br /><br />
Update:<br />
O.K. So the feedback has been great and I have read through a bit of it but I want to clarify my question by saying that I am looking for more information on how to actually go about setting my up my repositories, clients, server, etc.  I know that I could do a quick Google search and find dozens (or more) resources but I'm hoping that someone whom has experience with subversion and a client(I have installed tortoise) could suggest a good reference that will be reliable, and have quality content.</p>

Eric Sink has an
excellent series
on source code control aimed at beginners. For Subversion specifics, including setting up and administering a server, the
Subversion book
is a great resource, and includes a section with examples of a typical session with Subversion (checkout, commit, merging and updating basics).
Update:
I forgot to mention that for beginners, I'd also recommend messing around in a graphical client, which removes the command-line hassle from the learning experience.
RapidSVN
is a reasonable cross-platform client. You'll also find that common IDEs either come with Subversion support, or have plugins which can be installed, which allow most version control operations to be performed within that environment.
@John Millikin:
While setting up a Subversion server can be complicated, depending on one's general admin experience, don't forget that you don't need to do that just to mess about with a repository and get to grips with the basics - the client can interact with a repository in the local filesystem.
