Again as this is a games machine, do we need a keyboard and mouse?
The keys/joystick controls can be mapped to the dpads on the psp.
I dont see 1.8" hdd as good option, HDD has movable parts, and for portable device - i do not recommend it. The microSDHC card is much cheaper, and read/write is enough for amiga emulation. current maximum size of microSDHC is 16GB, which is enough too.
About the USB, and external devices. If you want to add tv-out port, then the ports for joysticks (for mp games) and mouse can be great addition. I really dont know where the ports location should be, but maybe under the UMD cover is enough space. I really dont know, But I dont see much benefit of TV-out without using 2 joysticks/mouse/keyboard.
