One idea would be just to get nice cream bedding to go with the carpet and then cream curtains, then with what you accessorize with will make the room mor girly, You can paint the wooden letters for her name, except when you go to hang them, attach pretty ribbon to it tied in bows at the top, you should be able to find some type of ribbon to tie it all togethor, every craft store has tons of ribbon, Also if you like butterflies, when my daughter was little we purchased these butterfly stickers from Highlights catalog, they are all beatiful colors and they are made from a thick vellum that you bend at the center making it a 3D effectand stick to the wall that way it makes it look like butterflies have landed on the wall.
You may also want to look for other "girlie" things, for the first few years, my mother inlaw had bought be 3 old fashioned bunting hats. Instead of having my daughter wear them I used them for decoration in her room.
There are lots of wonderful ideas out there, google baby girl bedrooms and I'm sure you will be able to find something that fits. BTW I LOVE any color red walls, I think it will look great. Good luck
