Why not run Nexus Mod Manager and install some mods that way? SkyUI is a great way to improve the look of the UI. I also like the adaptive HUD mod, which removes the HUD until you actually do something that requires it, like combat. There are a number of other mods that make the game look like, as you say, a proper PC RPG and not a console game. In SkyUI, I've decreased the size of the font, too.
