Here is my rough estimate for approach and berthing timeline. I checked and didn't find anything in:
- the NSF article that ChrisB just posted
- the SpaceX press kit
- this thread

... so I went to the CRS-1 thread from last October and based off of what I found there:

05:09:06 AM...02...08...33...59...Range: 1,150 feet; 180 degree yaw maneuver
05:14:06 AM...02...08...38...59...Depart 1,150 feet
05:22:06 AM...02...08...46...59...Range: 820 feet
05:32:06 AM...02...08...56...59...Depart 820 feet
06:26:06 AM...02...09...50...59...Range: 100 feet
06:40:06 AM...02...10...04...59...100 feet departure
06:58:06 AM...02...10...22...59...Capture point arrival
07:14:06 AM...02...10...38...59...Go for capture
07:22:06 AM...02...10...46...59...CAPTURE

Note again: the above is NOT today's timeline; it's from CRS-1 in October.

So, based on the above:
Capture - 1h50m = 250 meter (820 foot) departure
Capture - 0h42m = 30 meter (100 foot) departure
Capture - 0h24m = Capture point arrival

Now referencing to the planned 6:31am ET capture:
4:41am ET = 250 meter (820 foot) departure
5:49am ET = 30 meter (100 foot) departure
6:07am ET = Capture point arrival

Times are obviously rough estimates. I just needed to know what time to set my alarm clock for. Corrections welcome.

EDIT: thanks jcm for the confirmation I have now edited and refined the above information.

Press kit contains info re the approach. See http://forum.nasaspaceflight.com/index.php?topic=30700.msg1017366#msg1017366.

cheers, Martin

@Cmdr_Hadfield: Just caught sight of #Dragon, crisply white against horizon, sneaking up on us from behind. We're readying to grapple.

PAO Dan confirms they are ahead of schedule.....but it's a 11:36am UTC capture.

I think he said at the capture point at 1136, not necessarily capture

Looks like Dragon is performing a yaw maneuver.

#Dragon has arrived at the R-Bar and is now starting a 5-minute maneuver, performing a 180-yaw maneuver.

Nice feed Artyom

This maneuver is needed to place #Dragon's thrusters in the proper position for eventual rendezvous aborts.

The Yaw-Maneuver is complete and #Dragon is continuing its approach to the 250-meter hold point.
