It would be best if you cut in your ditches and form the crown before the gravel is delivered. The spread of gravel will follow your profile for better or worse, so it is better to have it profiled well before the gravel comes. Cutting in the ditches will give you material to form the crown. Then, when the gravel comes and gets spread, it will be pretty much the same depth from, edge to edge and in the middle.
Ditches are your friend. I use sumps/swales where there is no downhill for me to send the the water to.
I agree with shaping the driveway first. Get it where it works with ditches, diversions and culverts. Crown the driveway then see how it does after a rain. Fix any further issues with drainage when this is done then call in the gravel trucks. I recommend you go the trouble to find out which driver is the best at tailgating/spreading the gravel. A good truck driver can save you a ton of work. Particularly if you have few implements.
