Nice find. I've been looking for one without too much luck.
As for upgrades, well they are hard to come by.
The RAM card is a hit and miss on ebay and LEM (I found a 36MB card on ebay).
The hard drive uses a portable SCSI. They have not made anything bigger than 1GB unless you are lucky and find the very rare SCSI to IDE adapter Apple Made.
As for a floppy, you first need a dock of some kind that has the floppy port. Then you need to find a Powerbook100/Duo floppy drive. Again, hard to find.
Finally, for an external SCSI CD-ROM you will need a dock. Generally a mini-dock or Duo Dock will do. I am not sure if they made a Micro-Dock with SCSI on it. You will also need a HDI-30 adapter to plug in any SCSI device. The 'cool' SCSI docks are uncommon and most hold on to them or demand a premium.
