The MAF sensor is located on the intake pipe where it exits the air filter box.
i think the wiring harness is different >.
Unplug then unscrew the old one. Screw the new one in and plug it into the wiring harness. Special sockets that will help you to remove the oxy sensor are available for loan at many auto parts stores.
Depending on which bulb you need, either the local auto parts store or your Subaru dealer's parts department.

Your local auto parts store will recommend the correct filter based on the brands that they carry. --Ken
Try your local auto part store. The ones near me will read the codes for free. --Ken
Changing an oxygen sensor is awkward, not necessarily difficult. The answer really depends on your skill level so without knowing that my answer is meaningless. Auto parts stores lend a socket set for changing oxygen sensors and they do help some. Good luck! --Ken
That depends on the brand of filters that your auto parts store carries. While you are there checking out the brands they also have filter cross references that will tell you which filters that they carry will fit your Subaru.
Go to the auto parts store and get a manual for your Forester, like the Haynes. It has a full description of how to do the job. After reviewing the procedure, if you think that your skill level is up to the task, have at it. Otherwise, take it to a professional. --Ken
Go to your local auto parts store and get the Haynes manual (or similar) for your Forester. Cost about $20. Read and see if you feel that your skills are up to doing the procedure. Otherwise, leave this to a professional. --Ken
I borrowed ($30 deposit) an O2 sensor socket set from Advance Auto Parts. Works like a charm.
Unsure where you'll find the bugger, get your auto sparky to replace it (its a MAP sensor) as it can cause real headaches if it dies, engine rebuilds and such
