Just a bump to remind those who wanted to watch this; Launch is scheduled for 4:15 AM EST (1:15 AM PST) tomorrow (or a little under 13 hours from the time of this posting).
Their 'press kit' has a whole bunch of info on the launch and the schedule of events:

Mission Highlights
During the mission, Dragon must perform a series of complex tasks, each presenting significant technical challenges (timeline could
change):
Day 1/Launch Day: SpaceX’s Falcon 9 rocket launches a Dragon spacecraft into orbit from the Cape Canaveral Air Force Station.
Day 2: Dragon orbits Earth as it travels toward the International Space Station.
Day 3: Dragon’s sensors and flight systems are subject to a series of complicated tests to determine if the vehicle is ready to
berth with the space station; these tests include maneuvers and systems checks that see the vehicle come within 1.5 miles of
the station.
Day 4: NASA decides if Dragon is allowed to attempt to berth with the station. If so, Dragon approaches; it is captured by
station’s robotic arm and attached to the station. This requires extreme precision even as both Dragon and station orbit the
Earth every 90 minutes.
Day 5 - TBD: Astronauts open Dragon’s hatch, unload supplies and fill Dragon with return cargo.
TBD: After approximately two weeks, Dragon is detached from the station and returns to Earth, landing in the Pacific, hundreds
of miles west of Southern California.
I'm not sure how much of it will be broadcasted live via webstream, but we're probably looking at a good several hours over the course of the next few days.
