Couple pointers:

1. You do not need to setup a Condor "dedicated scheduler" to use 
dedicated resources.  The only reason you would need to setup a 
dedicated scheduler in Condor is if you must submit parallel universe 
jobs, i.e. jobs that require multiple machines at the same time. 
Typical examples of this are MPI or PVM jobs, usually on Unix - folks 
using MPI on Windows are fairly rare.  If you do not need to use 
parallel universe, e.g. just want to submit loads of vanilla universe 
jobs, you do not need to set this up. Maybe the "dedicated scheduler" in 
Condor would be better named "the parallel scheduler" :).

2. If you truly need to submit parallel universe jobs, you need to 
customize more settings than you mentioned below.  The easiest way to do 
this is to consult the example file:
  c:\condor\etc\condor_config.local.dedicated.resource
for the rest of the settings you need. It is well-commented.

Hope the above pointers help
