Virtual Server Allocation

I have a brand new Dell R610 with 2 x XeonE5620's (Quad Core , 12m Cach), 32GB Memorry, Raid 5 (3 x 600GB 10rpm).

I am using this new server to host 2-4 virtual servers that will contain: Kaspersky Security Center (managing 35 machines), WSUS, Spiceworks, Network Monitoring, File server (For all Office Cab files) and Symantec Ghost.

I know I can separate all of these onto 2 virtual servers, but I am considering configuring more, to separate the services.  Any thoughts or recomendations?

Also, can this server handle 4 virtual servers running 24/7?

Yes, you will have plenty of resources, rule of thumb, 5-6 VMs per Core, CPU is not often the bottleneck, memory is often the bottleneck, so you will have no issues with 4 virtual servers, with resources.

Separating services is a good idea, because if gives you the ability to take just a service out of production for maintenance, but be careful of virtual server sprawl, and depending upon your Microsoft licensing could be costly.
I would not exceed vCPU allocation beyond the number of logical processors that you have (which a guess would be 16 with 2x quad with hyper-threading) to avoid cpu cycle wait times.

Take advantage of Server 2008 R2 SP1's ability to utilize dynamic memory and you can set startup memory fairly low (512 MB is recommended for all newer versions of server) and specify your maximum memory that it could potentially consume.

Depending on RAID controller (battery or no battery for caching), hard drive performance could be the bottleneck if heavy I/O becomes constant. Overall, it should be a good setup for applications that you listed. Plan out your RAM requirements and start out low and add as needed.
