The answers to these and far more questions are available online.  Look
on www.beowulf.org and/or www.phy.duke.edu/brahma for links to e.g.
Kragen Sitaker's Beowulf FAQ (answers 1 right away, for example), The
Beowulf HOWTO by Jacek Radajewski and Douglas Eadline, the beowulf
underground, and of course the online beowulf book Doug Eadline and I
(with help from a growing number of volunteers) are writing.  In the
book (even in the current snapshot) I'm pretty sure that all of these
questions are answered in detail, for example.  The online snapshot is
on the brahma site.
