Share Your Space Challenge - My Daughter's Room

I am ashamed to post these photos of my daughter's room.  It is simply awful. As you can see we like Ikea, but with the limited amount of space in this room, we really need to use the space more efficiently. 

My daughter has ADHD and the professionals have recommended that she have open storage spaces to help make it easier for her to organize things.  We need help with everything.  I was thinking a loft bed would be a good idea, with a desk under it so she can do homework and read.  We need more shelves, we have a ton of books in this house and her bookshelf is already overflowing.   And don't get me started on her closet.  It's worse than the room.  She doesn't even know what she has anymore.

I know she would like a more teen vibe and less of a little girl feeling to her room.  She's 9, but shows like iCarly portray these really cool, out-of-this-world sort of rooms and she is totally into it.

And please don't judge me by this mess.  There comes a point where the clutter gets so overwhelming, I just shut down.  But I have finally gotten to the point where I am tired of it and I would like to see everything neat and organized.  I strive for this, but have come up short...very short...over the past few years. 

Please help.  It would be most appreciated and with any luck it would make life easier for my daughter and me.

I would like to make this room over with these pieces:

The STORÅ Loft bed frame $299
The LAIVA Desk - $20
An EXPEDIT Bookcase - $69
The SULTAN HANESTED Mattress - $199
The HELMER Drawer Unit - $39.99
The HEMNES Chest of drawers - $149
The SOLSTA Sofa Bed - $149
The MASKROS Ceiling lamp - $49

These items would be a great start to a new room for my girl!
