Regarding the two versions installed, check this: http://forums.adobe.com/message/5453566#5453566. I think the ID CC is the 32. I haven't used much the CC-64 and also haven't noticed much difference in speed. But others think different. Regarding requirements, I'll let others respond. By the way when I tested the CC in a regular monitor (17 in, 1024 x 768) I immediately saw what other users complained about the tiny menus. You really have to have a highres/bigger monitor to function properly.

Yeah, if you start the app first. What about when you double-click a file with ID closed?
It is very strange that users are forced to install both the 64-bit and
32-bit versions, and that there's no way to uninstall one of them. I
don't have such a strong opinion as Bob as to whether they should
actually drop the 32-bit version altogether -- that's something which
Adobe can decide. But definitely the user should have a choice! It just
seems quite shoddy to force us to use up our hardware resources to
install two versions of the same app for no reason without being able to
uninstall one. Plus the issues, as you say, of not obviously knowing
which app is being launched when you double-click a file.
I also posted a while back about more shodiness along these lines - the
brand new Adobe Exchange packager (which packages producers' scripts for
the brand new Adobe Exchange) actually fails to target the 64-bit
version of InDesign CC. Meaning that you can package your script, target
InDesign in Exchange Producer, not get any warnings, have your
submission "vetted" by Adobe, only to get users emailing you about why
your script doesn't appear inside the CC 64-bit script panel. I haven't
heard whether they've fixed that yet. So the lack of clarity about what
is being installed seems to reach right inside Adobe.
I never made one or the other the default yet it's the 64 bit version
