If I were you I would first get a free inspection. Dont do anything until you know what needs to be fixed. Get an estimate and come back here. I or some one else can then help you with what you need. Be sure to go some where that you or some one you know trusts. If the price seems high go elsewhere and get another estimate.
If you have drum brakes than I would not recommend doing then yourself without help. They can be very tricky. Your best bet would be to have someone you know do it that wont charge you much if anything at all.
Oh and yes it is much cheaper to do it youself. The shop I used to work in did a standar front break job for $79.95. Rear breaks were only 59.95 for drums and 69.95 for rotors. Of coarse trucks with 4 wheel drive were a little more due to the extra parts. This all included lifetime warranty pads, drums and rotors were cleaned and turned and sliders lubed, etc. We did breaks cheaper than anyone in town. Most would charge $100+ to do the same. However if you do it yourself you can get away with spending 9.95 on a set of pads and $5 on some slider grease. The only tools you need for front rotor breaks is either a hex or a torx head socket that fits your car. You can get one at a parts store for maybe $5. The people at the counter should be able to tell you what one you need for you particular vehicle.
One more thing. If you are hearing squeeking that is probably just the squeelers that tell you you need a break job but if you have been hearing them for a while than you may be metal-to-metal and that could mean new rotors which will raise the price considerably. But like I said get an estimate than come back here
