Your taxes paid for it, so you might as well get you money's worth. The Land Grant University's administer the Federal Farm Extension offices and among other things they have tons of info on canning about anything you might want to can.
Your pressure cooker, if you still have all the parts assembly, should work fine. Plate with holes for bottom to keep steam from break the jars. Rack for lowering in and lifting out the HOT, hot jars. Good seal. Pressure knob. Blow out plug in good shape? (Safety?) Long hot work but worth it. Enjoy.
