Hope we're caught up and my answers aren't too confusing. What's kind of interesting about many of these lines of questioning is that these topics are not particularly central to our beliefs, and we do not speak about them in any depth very often. It's not like we sit around with telescopes looking for Kolob or anything like that. We spend our time talking about things that are pertinent to salvation, things that probably do not seem so weird to others. Many of these things are simply not terribly important, and in my view are probably symbolic and analogies of something more eternal that we don't necessarily understand.
You may proceed to ask more if you like, but at this point I will probably not answer for a few days.
