Yet another ERAS question.....Should the paid jobs as "research assistant" I had after college be included under "work experience", "research experience" or both??

hehe, nothing on there matters except your step 1 grade and class rank, the rest is just filler.

I would put it under research experience as having more things under that is more likely to help your application then work experience. And research experience can be very important for getting into top programs.
