ICs with I/Os that are not 5V tolerant may need level shifting buffers. You will see these in many modern designs for the Amiga. However both the A600 and A1200 PCMCIA ports have TTL bus buffers that only pull up weakly above 3.3V, so you could probably get away without level shifters. A 3.3V regulator will be required to power the IC of course, but this is not a big deal.

I don't think there is much point in doing anything above "USB2.0 Full Speed" as I don't think the PCMCIA port has the bandwidth?

Well that's a relief, because the PCB layout and devices needed to support USB3 at 5 Gbit/s are very critical. Amiga wins again!
Can I use a USB 3.0 device in a USB 2.0 port?

Yes.
In fact, all USB 3.0 devices — technically called USB 3.1 these days — are also USB 2.0 devices.
