While you are in there, replace the oil filter housing gasket if you never replaced it and since you are asking about how to replace the alternator I am quite certain that you never replaced it. It's just 6 more bolts once the alternator is removed.

Hardest part will be to remove the clutch fan if you don't have the special tool. Remember the clutch has left hand thread so it righty loosey lefty tighty as you face the engine from the front.

There an excellent video on Youtube on replacing the Oil Filter Housing Gasket.
