Not sure about the docker support question, so I'll leave that to others

The release engineering types will have a more specific answer, but
OpenStack releases tend to be very much on time.  I haven't paid
minute attention but if they haven't been precisely on time it's only
varied by a few days.

If Ubuntu is your OS of choice I'd recommend 12.04 with packages from
their "cloud archive"
see https://wiki.ubuntu.com/ServerTeam/CloudArchive , they even have a
havana repo up (I'm using 12.04 and grizzly not sure what is in havana

Using your configuration management system of choice is usually best,
most have pretty good openstack support.  I'm most familiar with the
puppet way.  Going completely roll your own isn't that bad, most
people get hung up a bit on networking (even with community config
modules or cook books).  This this is good for conceptual discussion
about what implementation strategies meet your goals.  #openstack IRC
on freenode is excellent for when you trip up trying to implement
those plans and are trying to debug.

There's lots of moving parts, but once you get use to the layout and
terminology it's not too hard to find your way around.

Given the short cycle I'd do the initial deploy and test with havana
rc2 bits that are out now.  Named version upgrades don't require VM
downtime though they do tend to disrupt the control plane (there's
work to provide V-1 backwards compatibility so this goes away too, not
sure how close or far that goal is), going from rc2 to release should
be completely non disruptive.

http://docs.openstack.org has lots of good stuff, though it can be
challenging to know quite where to look.  Probably best to start with
Install guide and then the admin guides.  Note that the page will
point you to the grizzly docs but you can get to the latest pre-havana
docs (which may be incomplete yet) by swapping the "grizzly" in the
url with "trunk" for exmaple
