Can you point me to the stuff you're talking about on amazon.com? I kinda get the overall picture of what the room is gonna look like when all lights are in place (sexy:338

, but not sure exactly what stuffz to use.
Yeah, try searching "uplights" and you'll find stuff like this...
Ikea used to make some almost exactly like these but they don't seem to have them anymore. Cheap, bury them behind furniture, stick em in corners, you can use coloured bulbs (I used to have blue bulbs in 3 of them around the room in my place in Vancouver in ones like this, that let you control where the light goes a bit better [ame=http://www.amazon.com/Black-Metal-Swivel-Uplight-Plant/dp/B002JE7OFY/ref=sr_1_3?ie=UTF8&s=furniture&qid=1267406881&sr=1-3]Amazon.com: Black Metal Swivel Uplight - Plant - Can Light: Furniture & Decor[/ame]) 1 behind the tv, 1 behind the couch, etc.

You could use the new LED type bulbs in them, and though expensive, these remote controlled colour changing ones could be the bomb...

Make sure you don't go over the recommended wattage and don't set your curtains on fire.
You could halogens but they'll get hotter...

For the desk those Z Lamps are pretty nice, but also quite expensive. I use typical swing arm desk lamps and just point them at the walls/ceiling...

I've got nice brushed aluminum ones. You could load these up with LED bulbs too and get the same kind of easy on the eyes light as the Z Lamps at a tiny fraction of the cost... just not as sexy.
Quick example of reflected light. There's another lamp out of picture and you could augment this with some floor pots behind the desk, or in your case behind you, or whatever.
