I have worked with both Svn and Git, and I would choose Git anytime. Git is easy to setup and get started. Also, Git is much faster to work with than Svn, and I have a lot less issues with Git than with Svn.
Git is a distributed VCS, meaning that each user has its own repo, and later on push their changes to a central repo. This has many advantages against Svn that only has a central repo.
However, if you choose to use Svn I'd recommend that you use VisualSVN addin to Visual Studio and the VisualSVN Server to manage your repository.
As a side note, when working with Git, I have found that I do not have a need for any Visual Studio integration that I always had with VisualSVN. Git just works from the command line.
I have no experience with TFS, so I can't comment on that.

We use Subversion with VisualSVN Server and VisualSVN client plugin for Visual Studio. The server is really easy to setup and configure repositories and the plugin integrates very nicely with Visual Sudio (2005, 2008 and 2010 are supported).
VisualSVN Server also supports remote access via HTTP/HTTPS.
VisualSVN Server (Free) - http://www.visualsvn.com/server/
VisualSVN - Visual Studio plugin (Free 30 day trial, then $49 for licence per developer) - http://www.visualsvn.com/visualsvn/
I haven't used Git so can't comment on it's pros or cons.

TFS is good, but if you don't have license and want to try something different, go with GIT. I have evaluated GIT and it seems to work nicely with Visual Studio.
Besides, it also integrates nicely with VS2010 IDE as well and also it is primarily designed to have remote support as well.
Check the below URL, how use section which describes how to integrate with VS.
There are also many good articles/tutorials available on using GIT and managing the workitem lifecycle..... Some good examples can be found here..
The above article explains all the necessary command to work with GIT. The same can be achieved directly from inside the Visual Studio IDE as well. But knowing the basic commands comes in handy many times....

You could use Team foundation server which is pretty robust already and easily configurable with a ton of features.
I've never tried Git and have used subversion a lot prior to using TFS, it's got integration for vs2010 as well and has i think a 30 day trial which you could use to evaluate the product.
