Matt,
First I have some questions for you: Do you like the Canon AE-1P? Does it suit your needs? Do you plan to use it ever again? Assuming you answered yes to those questions, then send the camera into a trained camera repair professional and get the job done right. Accessing the mirror/iris control mechanism requires that the front plate of the camera be removed. This is a major disassembly and should only be attempted by an experienced technician.
While the squeek you're hearing does in fact come from the gear train you described (mirror/iris delay gear mech), it's not the only area of the camera that needs attention. It's simply the only area that's currently yelling for help. When any area of a camera starts to squeel it is an indication that the camera is ready for an overhaul. This is not just a "Cleaning" this is a full teardown, flush old lube out, new lube in and complete recalibration (using test equipment that I imagine you don't own) and then finally a so called cleaning.
As the current President of the National Associtaion of Photographic Equipment Technicians (NAPET), I'd be glad to recommend a repair facility in your area.
If on the other hand the camera is not important to you and you like to tinker without concern for the outcome, then by all means give it a go. Just understand that most repair technicians will not accept a repair that has been attempted by a customer.
Sincerely,
David Marsh
President, NAPET
