Currently NET February 11, 2014
ISS payload mass: 1,580kg (3,476lb)
Payloads: 1 GLACIER and 2 MERLIN freezers for experiment samples, Optical PAyload for Lasercomm Science (OPALS), the High Definition Earth Viewing (HDEV) camera, the KickSat CubeSat - which will deploy 250 (!!) KickSat Sprite picosatellites, plus incidentals and consumables.
This will also be the next Falcon 9 v1.1 to attempt landing the first stage after main engine cut-off (MECO) and stage separation. This is a major step towards manufacturing a reusable launcher, which will drastically lower launch costs.
If landing legs are available they are working with KSC for a place to make a land touchdown and with the FAA for permits.
If no legs are available it'll attempt another touchdown at sea, similar to the CASSIOPE launch.
