You probably won't need sway bars for a 1000-pound trailer unless your weight distribution is WAY off. Whether you need trailer brakes will vary by state. Some states require trailer brakes regardless of trailer weight, with a stipulation that the tow vehicle plus trailer be able to stop in 40 feet at 20 mph.
A good summary of trailer towing requirements by state can be found at Towing World's website:
