You want more servers than Clients as Clients will just be for testing things like RMS and certificates.. 2 win7 should be more than enough, I'm getting away with 1, You could possibly have an XP client to shake it up as some sites may still run XP clients here and there (Although I would consider upgrading them quickly) Save the resources for Servers.
