Good. I'd recomment a book "Managing DNS and BIND, 4-th ed" from o'reilly,
it will significantly shorten your learning cycle.

Yes. In fact if you make your server a master for that zone it will
never "go out" and retreive anything about that zone any more, it
has all info about this zone.

It will work if you add everything in that zone ( all 'A' records, 'MX'
records etc that your current ISP has.In addition you can add more items
which will only be found if one asks your server. That's called "split-dns"

In the long run that's probably more efficient, at least with all
resources not visible from outside.

There is a chapter of the mentioned book onlline, in fact just the
one you need :
