I'm not wholly equipped to answer your questions as well as I'd like, but I can tell you that there is an "edge" to the universe in some sense. The universe is simply a space that expanded during the big bang. Outside of that space there isn't really anything, so far as we know. There could be other universes alongside ours, but we really don't know right now.
The position of our planet around the sun is indeed the factor that determines its habitability, but the range of distance from the sun in which the Earth could remain habitable is quite large (as I've previously said).
You seem to have a natural curiosity for this kind of thing, so I encourage you to perhaps read some books on elementary physics or, if you've an hour or so to kill, watch this lecture by a physicist named Lawrence Krauss. It might not give you specific answers to your questions, but you would definitely learn a lot about the modern state of our understanding of the universe, how it came to be, how big it is, and how scientists are able to figure all of this stuff out.

I think you are well prepared, you just can't know that like all other mortals...
like you said "as far as we know" we may never know those things, maybe there is a universe of universes, maybe not...
I'm kind of curious about those things, universe, where we came from and where we are going to.... maybe too curious, maybe all that curiosity is going to kill me, or just leave me on a great depression...
all that bring me to the theme happiness... I think religious people are wrong for believing in everything they growed up listening, for sacrificing hours at week praying, for doing the good for other people not because they like or want to, but because they don't want to go to the Hell, for blaming people like gays or that have other cultures or religions...
BUT, I fell like, they a happier than I will never be a day, ok they don't live that life 100% thinking to the next one... but their are happy... and more delusional is to think that I may die without any answers, I (think) know that there is nothing after death...
