>>I do not like to post process much because I like to let my shots speak for themselves...
this is like saying, "I don't do a test strip in the darkroom, I just guess at the exposure and however it turns out is fine because the photo will speak for itself even if it is too dark or washed out etc," or "using multigrade filters or graded papers is cheating so I never use them."
Post processing is part of the process and is required for actually getting your photos to look "correct" and inline with your vision... it is not "cheating!"
I think all scans need to have a minor curve adjust, levels and appropriate sharpeing. Your scanner applies some curve to your scan which will never match your negative so you have to correct that, same for levels. In the A->D conversion you lose actual sharpness and you need to intelligently use a sharpening filter to gain back the original impression of sharpness.
PS is obviously best, but expensive, the Corel option looks good (I haven't used it) and GIMP is very good. Elements is kind of crippled (duh... they want to sell more PS)... GIMP is full feautred.
You really need a real curve tool IMO and Elements doesn't have one. Since it is free, just get GIMP and read a few tutorials and you'll do fine (I think the interface is harder for seasoned PS users than for new users).
I also don't get scans of my c41 b&w... rather get real prints for the proofs and scan my own for better quality... all the photoCD scans I've gotten are way too agressively compressed.
