The solar arrays deploy just as the pontoons are jettisoned. They are spring loaded, like spring snakes that shoot out when you open the can.
Ok, thanks now is clear. I will update the launch profile with this info. Only I'm still puzzled for the two pontoons left in orbit.....

The initial orbital insertion is not near enough to the ISS for them to be a problem; and they are low enough to the residual atmosphere that they reenter soon enough. They where tracked atleast a few times in the live threads, as far as I know. here are the tracking elements: Dragon itself - http://www.n2yo.com/satellite/?s=38348and here 2 "Dragon debris parts" - they have both decayed by now. http://www.n2yo.com/satellite/?s=38350http://www.n2yo.com/satellite/?s=38351

archipeppe6 thanks for creating these beautiful drawings. One small point about the last drawing (20) where the pilot chutes are shown floating separately and the mains deploy. I believe the pilots chutes remain attached to the hatch for the compartment where the mains are deployed from. This can be seen in the photo from the the drop test shown in this post ( link).

It wouldn't matter, as they would be in microgravity at that point anyway. A 'docking control station' could be installed in any direction.
That speculated window/port hole next to the docking ring would be too far away from the seated pilot to be of any use, I would think.
But this is all my speculation.
Note - the only image we have that suggests such an offset docking collar with window is this one (see below), and that seems to indicate that the window (if present) would be hatch-side. So his drawing is accurate in the location of the docking adapter offset.

Why would the pilot have to be in his seat for docking? The Commander was not in a seat for Shuttle dockings. You could imagine a small temporary panel, with hand controllers like the TORU panel, being installed next to that window for docking. T/Space had a similar idea for their vehicle, I seem to remember. But like you said, just more speculation.

Dunno why it would be needed at all. Dragon can do automated berthing.
In general, software is better than people. Window is just there for the view. Honestly, I think the only reason the dragon has manual controls as an option AT ALL ... is to be cooler.

Don't want to take this further OT, but a quick comment.
This was discussed on another thread. There was an opinion that NASA required a non-hatch window for docking operations.
Also, watch out for the docking/berthing distinction. The current Dragon does not automatically dock with ISS, it automatically rendezvous with it and the berthing is done by the Station crew. The docking of a future manned Dragon will not involve the Station arm. Even if it is able to dock automatically with ISS (which I doubt) I think there will still be a need for manual docking by the Dragon crew.

According to Ken Bowersox, Dragon Rider will be capable of fully automatic docking with manual docking available as a backup.

BTW, isn't the NDS port
compatible with berthing as well as docking? Isn't that one of the new features compared to APAS?

My English is not super, I entrust myself to a translator, but I hope you understand my explanations.
Version of the manned capsule Dragon drawn by you is wrong in the front. By films present on youtube is clearly seen that the capsule keeps the ring CBM, however, in its upper external part, has been added to the docking system NDS, the latter centered with the center line of the capsule.

The manned DragonRider capsule has the NDS systems placed offset, through bottom, according to the full scale mock-up introduced by Elon Musk to Charles Bolden in the last months. I suppose that the Youtube .video about that is quite updated
