The front ones are pretty straight forward and rather easy. Its held on by one bolt that is torqued to 116 flbs or so, once you remove that you need to pop the ball joint out of the knuckle and installing the new is the reverse. Also you will need to remove the ABS sensor which is held on by 2 bolts.
Make sure you have a torque wrench and a ball joint tool.
Now the rear ones are a WHOLE different story those are a PIA.

True, but he's changing a swinging arm and this affects alignment while the suspension is in motion. New arms will change this motion, although subtle. This is caused by new, stiffer bushings and ball joints. By changing to new ones doesn't mean that they magically fall back into line which is why alignment is necessary.

Depends on how far gone his old ones are. It would probably be a good idea to get an alignment in the somewhat near future, but he's probably not going to be chewing up tires until he does it. Will depend on his time and budget, mostly.
