Last Friday (14-Jul-2005) a thread titled "32/64bit ?" was started by 
"Bernie Betlach".  I wrote a fairly longish reply that answers most of your 
questions and there were a number of other good replies.  To save you the 
hassle, here's the link from the archives:

Gentle reminder: a LOT of good stuff is discussed on this list. Do a little 
searching of the archives before posting because it's possibly been 
answered before.  This saves you time, and us bandwidth :)

Cheers,

James
