I tried using that search before but i kept getting no results. I tried just putting 1 search field in and nothing happened. I didnt notice that the search link doesnt actually show you the results.

When im looking for a chip that has RX/TX pins is that "A/E/USART" instead of "UART"? Whats the difference between them?

What is the difference between program memory KBytes and KWords?

There are 3 chips that i think would do what i need. PIC16F648A, PIC16F87 and PIC16F88. All 3 seem to be more or less the same. Is "16F88x" the same as "PIC16F88"?
