Probably. All three will have their own OSM database and you will have to think about how to update data on all three separately.
Server3 will be my main interface and will reference server1 for tiles and server2 for lookup for geocoding and reverse geocoding. OR server1 will be my main interface referencing the other servers.
The "main interface" will just be a little Javascript and that could reside anywhere, even on a lightweight fourth server.
I am unsure if I will need all three of these elements as I believe that Nominatim encapsulates a mapnik server..
No, it doesn't. Nominatim's database is created with osm2pgsql just like that of the Mapnik tiles server but using a different table layout. So you really need all three.
There's ImpOSM, an alternative to osm2pgsql for tile servers, which has an accompanying product called ImpOSM geocoder, and the promise is that you can run geocoding *and* Mapnik tile creation off of the same database. This would reduce your server count by 1. However you'd need a map style that works with ImpOSM's output (or tweak ImpOSM's config to generate osm2pgsql-style output). Also, ImpOSM does not currently support incremental updates.
