How do you change a radiator in a 2002 Mazda Protege LX.?

The Haynes and Chilton manual appears to only go up to 1999 for the Protege, so I need to know if there is anything I should specifically be aware before I begin. I never replaced a radiator, but have done hoses, belts and the thermostat.

How difficult is replacing the radiator yourself? How much time will it probably take? I have no garage, so it'll need to be done over a weekend if that is possible. I was going to order it from Parts Geek. Is this online store any good?
None of you answered the difficulty level or the amount of time I should need to complete this task. None of you commented on the Parts geek online store. Do any of you read the questions completely before attempting to answer? Please, read and answer sincerely or don't answer at all. Thank you
