Mike, I am sorry, I meant that the AR server should be able to handle it. I would go with the 150 limit per mid tier. I haven't tested it to see how many it can actually run, but it can be pretty frustrating if you don't have enough of them to handle the load. I believe that you only need one AR server based on concurrent users SOLELY.
Fail-over and disaster recovery is a different ball of wax. Server groups are a great way to protect yourself. Based on what you are saying I would say a minimal setup would be 2 good webservers to handle the mid tier, one app server and one db server. But keep in mind that is minimal. Depending on how much money you have to spend I would double everything to start. Patrick has a pretty good recommendation.
