Gauges to go with ANY fuelling upgrade, preferably before the Smarty IMO.
I really dont see any need for better brakes. I live in the mountains and have never lacked for braking power even with increased hp. You could go with different pads but pads are always a compromise. To gain braking force, you often loose cold weather performance and often add some brake squeal. Considering winter is seriously cold where you live, and there aren't any mountians to worry about, I would leave the brakes stock.
