What breaker can 14 AWG THHN/THWN-2 Solid Copper Wire go on?: Up to 15 A. NEC 240.4(D) limits 14 AWG copper to 15 A of overcurrent protection whatever the ampacity table says.
How far can I run it before voltage drop is a problem?: At 15 A on a 120 V single phase circuit, about 35 ft one way keeps the drop at 3 percent, the figure an informational note to NEC 210.19(A) suggests for branch circuits. Try other loads in the voltage drop calculator.
Can it be buried directly in the ground?: No. It is not rated for direct burial. Run it in conduit, which counts as a wet location below grade, or use a direct burial type such as UF-B, USE-2 or URD.
Can I buy it by the foot?: It is sold on 500, 1,000, 2,500 ft spools or coils.
