Thanks for the links. I'll definitely check those out. I had thought of vinyl as an option to put some decals on top of the white paint, but I had never thought of using it instead of paint. I'm very new to a lot of this stuff, so I really have no idea what people normally do for some of this.
Other than the tmolding slots, I only used what I believe is called a double flute straight bit. My buddy had a nice set of several bits, and there were two of these straight bits that I used. For most everything, I used a 1/2" wide one that looked a lot like this http://www.amazon.com/Freud-04-132-2-Inch-Diameter-Straight/dp/B00004T7BL/ref=sr_1_14?s=hi&ie=UTF8&qid=1363895616&sr=1-14&keywords=1%2F2%22+double+flute+router+bit
For the hinges, door lock hole, and power inlet hole, I used one that looked the same, but it was only about 1/4" wide. I just needed something with a smaller radius for those.
I practiced a lot on some scrap mdf, and these bits turned out to be pretty easy to use. I basically just traced lines for where I wanted the wood to be a lower depth, and then just slid the router around until it was all gone. You can tell that I didn't do anything special to make straight cuts, and I had to keep checking to see if my fan/joystick/whatever fit into the area I just cut out. But as far as depth was concerned, the router bit did a great job of making the new depth perfectly flat.
