you will probably use a netter constantly. heck, our lecturers had netter plates in their lecture powerpoint slides. i liked rohen on nights i didn't want to go to the lab, and used it as a quiz with the numbered tags. however, don't get too jacked up about learning a bunch of stuff now... i started highlighting the stuff in netter that we had to know and after marking about 90% of the stuff in the book, i quit. it would have been intimidating if somebody told me we would cover that much stuff ahead of time.
if you want to study something, i would suggest drawing out arteries and nerves and trying to get that to stick (brachial plexus, pelvic nerves, etc)... there will be way too much stuff in netter and rohen to just dive into
