Alright, I'm a complete noob at working on a car, but here we are on a nice Saturday morning, and I have some time on my hands and want to change the breaks on my car (and save a few bucks while doing it myself too

). Firstly, the breaks (?) for the past few weeks are increasingly becoming squeaky everytime I stop, so I assume it's the breaks that need to be changed.
This car is a 2000 Civic SE. My questions are:
A) Is it the break pads that need to be changed, or are there other parts that need to be changed too? Are there any parts (or break pads) in the rear wheels that need to be dealt with too?
B) How long does it take and can it be done with a basic set of household tools (wrench, screwdrivers etc etc)?
C) What are my costs going to be?
Appreciate the help!
