Therefore, a well-leveled hero could have stats over 100 easily. But these are not that hero's BASE statistics.

With regard to the hero you mentioned that has a stat at 136 at a certain level, which would've been a 50-point increment (meaning the base would've been 86), there are items that you can use that will boost a hero's statistics temporarily (Wealth of Nations, The Art of War, etc.). Maybe this hero was under a bonus period for its stats.
Wrong. I've gotten a hero with 78 base attack from a level 5 inn. HE started with 80 attack, but I took a gamble with 1 of my few remaining holy waters and only lost 2 points to attack

78 is the max I've seen. There may be better. 86 is not out of the question.
