I am following the instructions on: https://www.arduino.cc/en/Guide/Windows
I plugged in the Uno board and L is already blinking. I put an LED in 13/gnd and it blinks as well. (On LED is solid lit)

Not sure what this means. Does the Uno board come with the LED Blink program loaded?
I bought a Make Special Edition Getting Started with Arduino kit from Radio Shack along with what turned out to be a 2nd edition Getting started book (Chip illustrations are 28 pin DIP whereas my Uno board has surface mounted package).

Never mind, I uploaded the Blink program and see it is blinking differently now (once per second).

Boards usually come with "blink" preloaded.
