Assuming that you'll likely be restricted to playing only public courses here are some tips:
It is OK to wear your hat backwards when on the course, but when dining in the clubhouse, you should wear it with the brim facing forward.
Music playing from your cart should not be so loud as to interfere with music on adjoining fairways.
Bring food & beer in your cart. 6 hours is a long time, and beverage cart service may be unreliable.
At public courses near large cities, do not let anyone at the club drop take the clubs from your car - you'll likely never see them again.
If you have any question while on the course, look for the ranger/marshall- he will be the old guy on a cart hunting for golf balls in the bushes.
Price shown at registration is not the fee for an annual pass - it's the 18 hole greens fee. Cart is included, but you'll need to give it back when done.
