Get plates first. that's usually a little more important :P.
Why are you going with an i3? From the list of things you want to do, it seems a less power-hungry machine like the atom would work flawlessly. You left a harddrive off the list. I'd recommend SSD's but if you are going to run CF, you can't expect a fast boot experience anyway... I'm not sure how fast "Carma" starts up.
