Help 4. Using a A/D in a PIC18F2550

First of all I would like to say thank you to everybody who helped me in my previous questions, "how to wire a Potentiometer" ,"how to wire a solenoid valve"and prototyping with a stripboard. Your help has proved really valuable to me.

This time my question is about using a PIC 18F2550 that I have with me. Particularly the A/D function. The value I am going to be entering is the voltage from the potentiometer. (0-5V)

so the questions I have so far are:

1) Is there a place you can recommend to find examples or tutorials on this theme?
2) Does the PIC 18F2550 needs any particular wiring (apart from putting I suppose the wiper of the pot to a port (any resistor needed? maybe not)

I know the questions seems too general so far but I am just starting to read the docs about this. I suppose I will have more concrete questions later.

Thank you in advance for all the help you can give me.
