No need to be embarassed; this is one of the most difficult things to do with Mapserver (the other is coordinate systems and EXTENT).  The Itasca Workshop demo is set up for Linux, so the paths are not very typical for a Windows installation. And some of the variables are relative to the Web Server's Document Root and others are relative to the Windows file system Root.  And for MS4W, some paths are "aliased" in Apache's hppd.conf file!

Here are some Windows-style values (I'm doing this from memory, so some tweaking may be required) appropriate for an MS4W install:

IMAGEPATH 'C:\ms4w\tmp\ms_tmp\'
	- relative to file system root
	- forward or back slashes ok; drive letters ok (but not "mapped" shared drives)

IMAGEURL '/ms_tmp/'
	- relative to Apache document root (C:\ms4w\Apache\htdocs)
	- for MS4W, this is aliased in Apache's hppd.conf file

map	"C:\ms4w\Apache\htdocs\workshop\itasca.map"
	- relative to file system root

program	"/cgi-bin/mapserv.exe"
	- relative to Apache document root 
	- for MS4W, this is aliased in Apache's hppd.conf file

root	"/workshop"
	- I'm not sure about this one, my guess is it is relative to Apache document root

And as Jeff M. points out, there are demos available on the MS4W site that are pre-configured to work painlessly with MS4W.  

Good luck!
