I wouldn't worry about the weight, if it is well balanced between the pannier, but the weight would be significantly reduced by leaving your laptop at the end destination.
I would definately recomend getting used to riding fixed before loading yourself up as well.
A path frame is a frame with track ends but a more relaxed geometry, bigger gaps between the frame and wheels and a longer headtube giving you a slower handling bike and a more upright
Position.
Definatley don't by a bike you don't like, for you budget and a bit of time you could make youself a half decent conversion, or by routing about at bike jumbles, here eBay and your local bike shop you could cut a lot of the cost of racks, guards and panniers.
