Hi.... Answer your questions:

-How well does KVM support Windows Guests? I'm already running a
Server 2008r2 and WHS 2011 (based on 08r2) machines at home which I
want to consolidate into this box.

Yes... In fact, I have some server running KVM with Windows 2008 R2
Enterprise. This VM's work together in a Cluster Enviroment... So,
this work well!

-Does KVM have a concept of virtual switches and and are they tied to
physical NICs? ESXi allows me to create a vSwitch that isn't tied to a
physical NIC so I can create a DMZ that exists solely within the host
system. I'd like to replicate that if possible.

Yes... You can use VirtManager to work with this feature...
