Musicman, if you're buying finished parts and going with the warmoth standard routs and buying hardware from them, it's all very easy - you'll need a hand drill, soldering iron, and good screwdrivers of the all the normal sizes.
Take it slow, double check what you're doing, etc. There's no measuring needed unless you're doing something unusual, I mean for instance putting a neck on involves four wood screws, a plate, some wax, a good screwdriver, and about 5 minutes time if you take it slow. it drops right in the pocket and lines up perfectly, doesn't take much expertise at all. You could have the whole thing together in a couple hours and another hour or so for fine-tuning the setup.
All of the 'high skill' stuff has been done for you - the frets will be awesome, their pre-cut nuts are fine (well the one I have is very good), neck holes are pre-drilled, etc.
One suggestion would be to carefully take apart and reassemble your strat - this may help you realize just how simple all of this is. Just take the strings off and start unscrewing things until you're satisfied, maybe take some pictures for reference. You could do a mod such as 7-way switching or something while you're at it.
Then you can spend that $200 on a more-expensive body or neck like a flamed koa top or something even more ridiculous, and make us all jealous. Several board members are being driven slowly insane in this way.
