First off,I didn't know you could get a local machine with >1.2 TB hard disk space 🙂
Second, to get just a variable list, can you try this?
*****************************************************
data varlist;
set <library.datasetname> obs=1;
run;
proc contents data=varlist;
run;

As for the SASV9.CFG file, you should look for it in your SAS s/w folder. Try C:\Program Files (x86)\SASFoundation\9.2\sasv9.cfg .. or something similar, once you get to the path, it musn't be difficult to find. Unfortunately, I don't have a local installation.
Check this article - http://support.sas.com/documentation/cdl/en/hostwin/63285/HTML/default/viewer.htm#a000104286.htm#worklib and search for 'SAS Default Folder Structure'. The default path is listed there.
Now once you find it, how you determine 'sufficient' space, I cannot say.
