Two 120 guide number shoe mount flashes (Sunpak 383, Vivitar 283 and 285), two 30-inch umbrellas, two 6-foot light stands and umbrella adapters, a few sync cables and a hot shoe adapter should get you started.
Or, instead of buying components separately, you could try one of the two-monolight kits
from companies such as B&H Photo, which sell for around $300.
