Ghostly ceiling fan and light

[url]http://s80.photobucket.com/albums/j165/SethNaga/?action=view¤t=DSC00295.jpg[/url] As you will see from the picture above, the room does not have enough lighting. There is only one light in the ceiling that too focused on the fireplace. The room size is 17 X 20. There is no other light in the room. Is there any way I can illuminate the room better through better fixtures. Also I want to put a fan in the center of the room. The room sits on top of the garage. Is this possible-DIY ? Thanks for your help

Here is my dilemma. I am trying to hang a new light fixture, followed the way it was done previously, but it is not working. Here is what I have, two switches, one is a dimmer switch. In the plain switch, I have a black wire on the right side of the box, a white on the top left and a red on the bottom right. In the dimmer switch, I have a red on the left top attached to a red in the junction box, a red and black attached on the right top, the red attached to a black from the box and the black attached to a black from the box. In the ceiling, I have a red attached to a red, a single white, another single white, and two blacks twisted together. On the fixture I have two separate brown wires. Can anyone help me figure this out or is it time to call an electrician? Thanks in advance for your help.
