If this is your first camping trip, consider taking a trial run close to home.  Stay at a campground with all the amenities (toilets, showers, fire places & drinking water). You'll see what it's like to cook, wash & sleep outdoors and that will help you plan and pack for more trips.

Setting up camp is a matter of choice, if you like a quiet camp where you barely see anybody all day or in a Holiday Park or campground that you pay per night.  Usually you are told where to set up your camp, but you have the advantage of amenities etc.

If you are setting up camp in the bush or forest with nature, try not to set up camp in a low lying area like a dry creek bed, if it rains you will be swimming.

Look up and check for any branches that are overhanging, avoid camping under them as they can break off.

If its hot weather place you tent so it will get shade in the afternoon and it its cool weather you may want your tent in the sun in the afternoon.

Look around for firewood you will need it for your camp fire. It is much more convenient if it is within walking distance.

Consider other campers; they may not appreciate you camping to close. If you are not sure ask them, most people won't mind, they may be leaving soon anyway.
