New Amiga toy

Over at BinaryDinosaurs Towers I was 'slightly' pleased to get sent an Amiga 4000/040 that's been tricked out with a CyberStorm 3 68060/FastSCSI II CPU card and CyberVision 64/3D graphics complete with CD and drives. It's yellowed a lot so I'll be digging through the recent archives on 'curing yellowed plastic' that I foolishly ignored but the main question is on disk cloning. It's boot drive is a 2.5gb Fuji that needs percussive maintenance to get it to run so I'm in a need of cloning it ASAP. I've got a known good 2.1gb Quantum Fireball that I want to transfer the boot disk contents to, so far my experiments with linux (aside from dd) haven't worked since the drives are different sizes. Any CBM experts got any pointers for me? The current boot drive has lots of things on I want to keep though upgrading the OS to 3.5 would be nice since it has more internet flavoured tools. This brings me to another question - where can I get an ethernet board for this beastie?
