tx & rx pins

SouthernAtHeart:
Can I use digital pins 0 and 1 just like any other of the digital pins?

Yup.

Does it just mean that I wouldn't be able to use the serial port back to my pc to get serial.print commands?

Yup. You may have problems uploading the next Sketch. Holding reset until the upload starts should get you through.

what about analog pins, how do I use them for simple digital pins, or can I?

They are accessed in exactly the same fashion (pinMode, digitalRead, digitalWrite). The pin numbering starts at one more than the last digital pin. For example...

The last digital pin is "13". Analog pin "A0" is also digital pin "14". Analog pin "A1" is also digital pin "15". Etcetera.
