Solved my own problem. I just changed the "VMWare Virtual Infrastructure Web Access" Service to start w/ a domain account. Now I can login using any designated domain account under my local administrator group.
Couple of notes:
Service account needs modify access to "<install location>\VMware\VMware Server\tomcat" <-- You could probably get more specific w/ permissions, but I'm too lazy to figure out what files it needs modify access to.
Adding users or groups from my domain is still an issue, but with this I can add a local group to my system and add users/groups from the domain to the local groups to break down permissions if I wanted to.
