Please bear with me. I'm an AI newbie, more used to working with Quark and
Photoshop.

I just posted a question regarding rulers, but after returning to the
document, I realized I need to know a bit more than that.

First of all, when creating a new document, no matter what size you select,
you are set on an unnecessarily large canvas (something like 400 inches
wide) -- making the document's scrollbars virtually useless, as even the
slightest nudge pushes the viewable document area out of bounds.

Why is the canvas so large? Is there a way to reduce it to something more
fitting with the document size?

Also, there are two outlines provided for the document. A solid black one
that fits the specified document dimensions entered, and an inner light grey
one, that is in no way aligned with the black (it's not centered or even
symmetric with the black outline, and just seems arbitrarily thrown in).
What is the purpose of that inner grey outline, and can I manipulate its
dimensions to use it as a bleed indicator?

And last but not least, the question I asked in my other post... a
newly-created 5" document will be arbitrarily placed onto the canvas. In
this case, it begins at 0.5" and ends at 5.5" across. How do I tell AI to
place the document at x=0, y=0? Do I have any control over where the rulers
begin or end in relation to the document?

Thanks,

Erik
