The minimum assignment from ARIN is actually a /22, which will only be
given to multi-homed end-users who qualify
(http://www.arin.net/policy/nrpm.html#four3).  Other than that, the
smallest assignment is /20.

Regardless of where their IP's come from, all they have to do is
announce them to their upstream providers using BGP.

Yes, they can apply for an ASN number as long as they can show ARIN that
they are in the process of bringing up connectivity with more than one
ISP.

ARIN's web page is actually pretty easy to navigate for finding this and
all the other information you will need.  I would suggest checking it
out.
