If you want a purely MS solution the use NLB to configure the load balancing and then DFS-R to do the replication of the data.  Alternately you coudl use robocopy to accomplish the file copying.  Note in IIS 7 the configuration is an XML file not a configuration DB like in previous versions.  

Here is an article on the IIS 7 configuration settings.

We also have 3 web servers load balanced at my company.  We use redundant Cisco ACE load balancer configured to do a Get request every 15sec for a specific txt file name on the root of the website.  If we want to take a server off of the load balancer we can simply rename the text file if we need to reboot or isolate it for testing purposes.  I have this down to a button click on a powershell form.  It has worked out very well for us.

As far as file synchronization goes we have been looking at RepliWeb since we need something that will let us replicate as well as have a work flow from Dev to Stage to Prod.  The whole Microsoft load balance and DFS was more than we wanted to administer or have issues with.  Are web server are currently work group servers.
