Replacing shocks is horribly simple. The front shocks have one nut at the top in the engine compartment and two at the base in the lower control arm. The top nut should have two nuts "jammed" together to keep them from coming loose. Using two wrenches, just pop them loose (may be rusty). Then remove the two lower bolts and it will simply slide out the lower control arm. You may have to lift the car to allow you room to pull the shock out the bottom. Removing the wheel makes things easier to reach. To install them, just reverse the process. Simple!
In the rear, the upper mount bolts can be hard to reach, but get a wrench on the bolt head on top of the mounting pad and use a deep socket on a ratchet to loosen the bolt from the bottom side. Two bolts each shock. Then all you need to do is loosen the large bolt at the base of the shock which mounts it to the axle. These are typically rusted tight, so have lots of WD40 on hand and a good long breaker bar for your socket. If you have an air ratchet gun it could be useful here.
If it won't budge, you can take it to a muffler shop and have them torch the head of the bolt off. This will destroy the rubber mounts but that's okay since you should get new ones with the new shocks. Again, to replace them just bolt in the new ones. Use new bolts all around in the rear since they take a lot of abuse and using new bolts at the top rear will make getting them started and tightened properly much easier. Don't forget to use lock washers on the rear upper bolts.
