You need a return or onward ticket and proof of funds (THB 20,000 per person or THB 40,000 per family, though this is rarely checked in practice).
The 60-day visa-free stay can be extended once for 30 additional days at any Thai Immigration office for THB 1,900 (about $55). The Chaeng Wattana office in Bangkok and offices in Chiang Mai and Phuket handle extensions in 1 to 3 hours.
