Wheelsets are the most obvious, albeit not really cheap, way to shave pounds. Sadly, you didn't really buy a light frame to begin with, so I wouldn't obsess over it.
Regarding learning to ride fixed with no brakes... ********. Do what you want after you know what you're doing.
I have test rode a Rush Hour, perhaps an '06 in '06, it was a nice grey - it's a fine cycle in singlespeed mode. You should be fine. Do some curls with it or something to get that ground to shoulder pop down pat, mang.
