I'm a big fan of targeting both sets of amylase enzymes when brewing belgian and German styles but I don't think you need the 65 rest. I'd also drop 62 back to around 15 minutes.
1012 would be the maximum FG I would aim for. 1008-1012 would be an acceptable range for my palate. A 15 min rest at 62, provided your thermometers are in good shape, should see you attenuate to that pretty easily.
