Ok, so I take it that you recommend the evaluation board and using the free Keil download.

However, I'm still baffled by some simple things (perhaps I am not finding the correct section in the datasheet); what parts do I need? If I were building this myself, I would guess i need the microprocessor and an external EPROM? Or could I program just the microcontroller itself using its onboard memory?

I'm sure that someone here must have a straightforward list of what you need to do a simple "Hello World" equivalent in microcontrollers. Thanks in advance.
