Your Ceph question is probably answered by

Yes, nova-compute uses Glance. nova.conf has a [glance] section.

Yes, Cinder manages volumes. No, it doesn't boot anything; Nova does that.

Yes, OpenStack services normally communicate via API (there are exceptions, such as Ceilometer getting samples directly over the message queue).

I suggest you read an introductory text about OpenStack and perform a manual installation. Most of the questions you have asked so far will be answered, and probably most of the questions you plan to ask in the future.
