While the pulleys LOOK like they will work and some even bolt up (Read Water pump), they won't work without reworking ALL the rest..Alt. pulley is usually pressed onto the alt. and replaced when you replace the ALt. So, I'd think the entire ALT would interchange, but the BRACKETS will not...
As for the PS pump? yes, the PUMP will work, but you will need the BB brackets in order to mount it up to the BB...
