Website Deisign, Version Control, and WordPress

Hello, I have just started to created my website using wordpress. This website is going to have very minimal development other than what wordpress already includes, some minor code changes I will be making, and perhaps later on outsourced code changes. The majority of the changes that will be made over time to this site will be maybe CSS changes and HTML changes.

I am wondering if anyone has any recommendations as to whether or not it is worth incorporating version control when you are using wordpress? The versioning control will help a lot any time changes are being made, so I can see exactly what changes and perhaps go back to old versions if necessary. Unfortunately, however, I am worried that because wordpress plugins or because of the way that wordpress works, it will periodically modify perhaps dozens of files at random times all of which would need to be checked out under version control (or else they would fail to get modified, maybe causing errors if they had to).

Does anyone know if versioning and wordpress will mix ok? Has anyone else used versioning and wordpress? What are other people using for web site source control? (If at all).

Thanks.
