I think it is easier to load up a good quality sim and experiment at different flight envelopes to get a better understanding of this topic.
Not to offend OP but it does not seem like you have a very clear understanding about AoA and wing loading.
Some of the most useful things I ever learned for flying were in an old ww2 fighter sim, with an AoA indicator turned on. This won't teach you about weird issues that arise from the positioning of the AoA sensor but you will learn the concept far quicker than you would just trying to hack out a solution by reading textbooks.
Try unloading the aircraft (push the nose down) and mess with the flaps at varying speeds and watch what happens to the AoA. Then do some stick pulling at various speeds (again messing with flaps) and watch what happens to the AoA.
I believe that you will probably start to understand AoA and stalls better, though don't count on sim stall characteristics being very realistic. The AoA figures experienced while maneuvering are generally pretty good representations of reality though.
