Windows 2008 R2 SP1 Standard should be fine.  You will require an SQL database - you can use Express but I'd suggest SQL Standard 2008 R2 on a dedicated server for performance reasons.  Your SCVMM can be a virtual machine - there is no need or benefit to having it a physical machine, since you can always use Failover Cluster Manger or Hyper-V to turn on guests.  Similarly, you could use VCenter Client to turn on VMware guests

If VMM is installed as a guest, it becomes highly available - but note that you cannot have more than one VMM installations.  Hosts can only be configured to talk to one VMM server at any one time.

Install SCVMM on a dedicated server (i.e. don't share it with another app), 4 GB RAM will cope with about 1000 Virtual machines just fine.  If using a Virtual machine, the default 40 GB hard drive will be plenty.  Give it 2 VCPU's.  Connect it to a database server running on a different virtual or physical server.

If you're going to import VCenter Servers, please ensure you install the VCenter Client on the VMM server.  SCVMM does not officially support ESX 4.1, and the ActiveX libraries will not work.  Installing VCenter Client will install newer, more up to date ActiveX libraries.

Hope this helps.

my intention was to use virtual SCVMM as a mgmt server for Hyper-V hosts where XenDesktop virtual desktops are going to be residing. was going to use 1vCPU with 4GB of RAM, 40GB HDD and library on a presented LUN with enough storage to cater for my ISOs / templates.

now that you mentioned 4GB RAM would cope with about 1000 virtual guests just fine, is there an official KB from MS stating the limitations of SCVMM 2008 R2 in terms how many hosts / virtual guests it supports ? as i am looking at provisioning thousands of virtual desktops down the track ?

I'm not aware of a white paper from MS.  Right now I am managing 219 Virtual Machines through VMM, and I'm using 1.4 GB of 4 GB RAM.  We have plans to be running a whole bunch more - well into the thousands.

The good thing is that you can always increase the memory in future :)  Windows 2008 R2 Standard will let you use up to 32 GB RAM.
