Changing the Alternator is a pretty straight forward job.
You could pick up a Haynes Repair manual Subaru Outbacks at an auto supply store, but if you're comfortable changing the oil on your car, I'd think you could handle swapping out your alternator.
First you'll need to loosen the alternator belt. By marking the adjustment screw with a felt pen you won't have a problem getting the belt to the correct tension (if the belt was correctly tensioned to start with). Then you remove two electrical connections- one plug-in and one with a nut (10mm?). Next you have to remove the metal belt guard. The alternator is held in place with two bolts. Be careful with the right bolt (looking from the front of the car), there is a nut in back that can drop down into the engine if you're not careful. Other than that, the old unit lifts right out and the new unit goes right in.
Of course I'm recounting this from memory, so I may not be 100% accurate, but it really is an easy job.
Hope this helps.
