the best thing to help would be a 'Haynes repair manual', avialable at your local auto parts store. but replacing a water can be difficult if your not particularly mechanically inclined, because it often requires the removal of several other componets as well as flushing the cooling system

If your looking to replace them, wich is what most do today, it is cheaper to purchase a axle with new cv joints than to rebuild them. It is a very simple job in todays cars, remove tires remove lower tie rod , remove nut in center of the rotor and pull wheel assembley to the side hanging from the strut, pull axle out replace the transmission seal, push new axle in. When putting wheel assembley on, use a hydraulic jack on bottom of the rotor to push it to the axle splines and put the new nut on .

This is a job for the dealer or cerified mechanic. The front cover and timing chain needs to be remove to access the water pump mounted behind the engine. The pump is driven by the timing chain and timing will need to be reset using special tools.

There is a heat sensor located near the thermostat that goes directly into the block. Get a Haynes or Chiltons manual.

The thermostat is probably bad and causing your overheating. If that is not hte problem, then it would probably be your water pump.
