What about amigaforever?
It comes with all ROM images (so you don't have to copy them across, and if you've got 3.0 on the A1200 you won't be able to use OS3.5+) and workbench disk images, as well as lots of emulators and some pre-set environments and Amiga-PC transfer tools.
BTW Amithlon is what you'd probably want, but its unfortunately illegal to buy it now :-(
