Very, very nice haul!
OWC (macsales.com) have a software driver for large disk support; I think it's free if you buy a large drive from them, otherwise $25. The other options are to use a PCI IDE or SATA card, or a PCI USB* or Firewire card with an external drive. In either case, it's still worth checking whether a larger drive will work with the specific card.
* remembering of course that you only get USB1.1 speeds under OS9.x.x and earlier.
No, that won't help.
