I almost got a round crib, but ended up going with the Bratt Decor Jane instead because it converts to a toddler bed (Plus it is soo cute
) I really like your choices, although I am a huge fan of the pink and pastels thing...plenty of time for her to have a sophisticated room when she is older, for now I want a sweet babyish room! 
Btw--no harm in planning ahead!! i'd be picking out ALL of my stuff ahead of the time if I was waiting until Jan to TTC!
