I would say '- CentOs 5 (64 bit)" JUST because it's a 64 bit operating system, which offers the best performance in almost every aspect, plus 64 bit offers support for upto 8 Gigs of ram, versus 32 bits mere 4 Gig support.
IF your planning on running multiple sites, with high volume then I'd definatley go with centOS 5/64bit.

If you don't need that much speed or performance, then I'd say CentOs (32 bit).
