Anyone have any bedroom decorating tips?

OK, I'm thirteen, and today my parents and I are going to be moving around furniture and such. I have a large, very heavy TV, that we're going to attempt to put on milk crates, so that I don't have to sit on the floor to watch TV. I also have an electric keyboard, and three guitars. I also have a saxophone that I have at school, but I have to bring it home for a concert I will be playing in next week. There's a hamper, and a fan on my floor, but the fan is lifted each night onto a chair so I can have it on when I sleep. My bed is too high for a fan to be sitting on the floor, and I get anything from it. On my dresser, I have a mirror, and on that mirror, there's pictures, a movie ticket, certificates, and a poem. There's also perfume, jewelry, my Edward and Bella dolls, my nail stuff, my makeup, my hair stuff, my deodorant, lotion, some pictures in frames, a mini mirror, two Cullen crests, and a lamp. On top of my TV are my remotes, a cable box, a DVD player, and a VCR, and a picture of my boyfriend. My old bedside table is behind my door with my trash can under it. On my headboard, there are two compartments for things, and in one, I have some journals for multiple projects I want to start, a book light, my old gles, (long story about the gles. To cut it short, I can't read with my new gles on, and I have to read with my old gles on.) and my flip video camera. In the other compartment, I have a math stencil I found on the bus, and am returning to the teacher on Monday, a book light, my DVDs, and my music case. In between them, I have my library books, and my gles case. On top of my headboard, I have my alarm clock. Covering my walls are Twilight posters, a calender for the countdown to Eclipse, a regular puppy calender, a picture of my father, a 3D picture of a ship, and a stitching thing my grandmother made the day I was born. There's also a few sweaters hanging on nails, and two cork boards. In the top right corner of my room, my fan, my old school backpack, and two guitars are there. On my desk, there's a lamp, a pencil sharpener, a lava lamp, and a basket of junk. In a container that's connected to my desk, I have my board games, and my writing binder. Under the table where my keyboard rests are my shoes, they're in a small container, then my art stuff in a pink container. On my bookcase are my books, of course, some magazines that I hope to make into a collage for my room, my yearbooks from fifth and seventh grade, some music books, a Twilight bucket holding some stuff, a broken basket with another smaller basket inside holding twine and beads, it's on top of a wood shop project I made last year, which was a box, and it's empty. Those things are on top of a box, which holds tons of things. next to that is my science project I have to bring to school Monday. On my hanging shelves that my grandfather made, there are figurines, a small set of drawers holding a few things, such as my sewing equipment. Then my memory box, and some things from my dad. I also have my snow globe collection on it too. On my other shelf, there's a Wicca shrine. On a little table next to my dresser is a small table with a little purple lined basket. That's empty. I can't paint, wallpaper, or buy new furniture, but I'd like some tips on how to make my room seem bigger. The first thing I see when I walk in is my bed. That's annoying. Please help me out, and sorry for the lengthy explanation.
