bsz: Try the 28c64 EEPROM for a start:
http://www.atmel.com/dyn/products/product_card.asp?part_id=1900
Atmel does also offer various flash types etc. And there more manufacturers.
I good start for a flash-card would be the 29c040. It holds 512kbyte and costs just around 3€. No external circuit required to program it, a direct connection to the cpu bus should be sufficient. But you have to take care of the additional address lines..

SRAM requires an external battery, flash does not.
In fact the hardware of a flash card is rather simple - its just the software that makes things complicated

Yessss! A good idea! (SRAM should be even better)
Have you seen the schematic of RAM expansions of Solder?

You should not use eproms anymore - there are flashroms and eeprom which are pin-compatible and much easier to program.
