AFAIK, SSSProgman is the one program that really eats up the space. You should be alright if you install everything but SSS.

There is a slight learning curve but I don't think its anything too tough once you start playing around with it, DIS is pretty straightforward.

If you got it running and are having problems with any of the programs let me know I can try to help, or post up here.
