on the younger girl's side, you can put a cute white bookshelf(or use the farm house painted all white) where she can arrange her care bears and books. Then use white wall shelving(Target) on other side and put butterfly and frog pics or art in white frames.
as for the rest of the room, there is SO much you can do with pink. i am currently planning my little girls room(antique ballerina theme). since you have such a gap in between the ages, I would do a nuetral type theme such as stripes and polka dots.
get matching striped comforters for both beds and use polka dot bed sheets.
here is an adorable inexpensive one:

some of the white frames you can paint stripes on to match!
also,with that comforter, id use these polka dots on the wall to bring the plum in. just do one accent wall,not all over.
