Did MJ figure it out? (Spiderman Spoilers)

[B.Serum]

I bet $100 she knows, if for no other reason that thus far Marvel movies have been (loosely) using comic book storylines as the basis of their plotlines. M.J. found out about Peter/Spidey in both the Mavel and Ultimate continutities, though they found out in different ways.

I think you’re right as to the “Hey, wait a sec…” look on her face after kiss at the end of the movie as being foreshadowing.

I though tit had to do with the similarity between Spidey saying something along the lines of “I’ll always be a ‘friend’.” and then Parker saying “I’ll always be your ‘friend’.”

No, the tits had to do with it being Kirsten Dunst, so they had to find some excuse to at least show nipplage through the shirt. Why do you think it was raining in that scene?
