If you have never built one of these before then I strongly sugest you get yourself a good how too book. There is one called, I think, Building the Kentucky Rifle. I've used it before. I'm a bit of a cheat and always purchased my stock pre-carved, that is with the barrel channel inlet, the ram rod hole drilled, and the stock rough shapped. I've inlet two barrels from scratch in my lifetime and neither was a whole lot of fun, and both were a whole lot of work, but very satisfying once done. I personally wouldn't touch trying to build my own lock, butt plate, or trigger and trigger gaurd, just because I'm not that good a metal smith, but I have fashioned my own odds and ends like the nose cap, side plate oposite the lock, and the wedge plates, and yes they have a special name but I can't think of it right now and probably couldn't spell it if I could think of it. I built several kits prior to taking on the semi custom scratch job. All in all it was a lot of fun, even with all the work, and very satisying once they were finished. I scratch built two caplock and one flintlock rifles and one flintlock pistol. I wish you the best of luck.
