I think I can generally reason my way through the blood type passages, but is there anything key to know about this stuff for the mcat...any input would be appreciated.

What do you mean? The only thing you need to know about blood type is the genotype for blood. The genes for each type are:
A: IAIA or IAi
B: IBIB or IBi
AB: IAIB
O: ii
...and you have to know that i is recessive, while both IA and IB are co-dominant. Know how to cross any two blood types together. For example, a mother with type A blood and a father with type AB blood can have the following genotype children:
IAIA, IAIB, IAi, IBi [because the mother could be IAIA or IAi]
Phenotype it is: A, AB, A, B
...that's it 🙂 Good luck!
