So big?

What size ID numbers (I guess 16 bits should be enough)? What kind of values?
where are the values coming from? What is the frequency of sampling.

Not enough information to give an answer to that.

Start with a 16F876. With it's compact packaging (28 pins), self modifyable
program memory, and built in USART, you should be able to handle the memory
storage and data transmission with little more than the part and a RS232
level converter.

As to the rest, you didn't provide enough information.
