I have the exact same floppy drive from analogic computers and have played many amiga disk games. You can also use relokick disk to make the system boot to any earlier kick start which will help with some older games. What you do need is a keyboard though to play non cd32 games - even if it is jut to press p to pause them.
I think you can get James Pond 2 on the cd32 - not sure if there was extra music or levels for that version.
Don't know if you like pd games but I created a compilation disk for the cd32
