Standard practice here in northwestern PA would be to remove the topsoil and then bring in the gravel. If you don't remove the topsoil and have any rain or, frost you'll be sorry. The first driveway I put in I used my father-inlaws' L4200 w/loader and 60" tiller. It worked great. Tilled it first, then removed the topsoil and stockpiled it for later use. If your land is naturally wet you may want to haul in a coarse gravel with softball size stones (sometimes called "overrun") for a good base then a crushed or, screened for the top and finish grading.
