I think I agree with both of your squicks. With the first one about bottoming, In my opinion, it's most convincing when both characters are strong no matter who is the bottom. Because, obviously, it's not just going to be the weak character who is the bottom - and with these two, neither is really weak. I prefer fics where the person who is the bottom is more 'I want you to fuck me' than all submissive and girly. It just seems a lot more realistic that both of them would be more open in directing their pleasure, particularly if it wasn't the first time they were with each other or with anyone at all.
