I would suggest a practice day. You can follow a favorite player and listen to him and his caddy talk and figure out the course.
I also highly recommend watching Ayers on the driving range and putting green. See how pro's practice with a purpose and fine tune their game.
I always thought it was jest to see pro's hitting approach shots to a green away from that day's pin only to see it be the Sunday pin.
As for everything else, website will have details on yes/no for chairs, umbrellas, coolers, bags etc.
Best generic advice is to wear comfortable shoes, hydrate and bring a hat and shades. DO NOT BE THE WHO WEARS HIS GOLF SHOES WHILE WALKING THE COURSE!!!!!
