Headroom is to account for various tolerances and to make sure you can always get full rated thrust. It depends on the specific conditions, but headroom is usually between about 0.5% and 1.0% N1 (figure roughly twice that amount of thrust).
The max rating available for the CFM56-7 on the 737-800 is less than the max rated thrust the engine is capable of (used on the -900ER). On the shorter 737-6/7/800 models, the max ratings are lower to account for the ability of the tail to counter the thrust pitch-up (shorter aircraft means less moment arm for the tail surfaces). On the non-FADEC 737-300/500, this thrust limit was via a physical block in the throttle - on the FADEC NG this is done with a rating plug on the FADEC.
Correct about the Classic, which is what I fly at the moment. My experience on the NG variant is still limited.
And according to the 737 technical site, the forward stop - or just short of it - is actually 27K bump, available as an option.
