You should be fine, unless there is some other big draw on the panel besides planer and dust collector. I have a 60 Amp sub panel with almost identical power draw and it's all working just fine. Having said that, if you think you can shove a 20" wide oak plank through the planer and hog off a 1/4" think again, just use common sense. You can't compare an air compressor to a planer or table saw, the compressor always has to start under heavy load - the jointer/planer not. Btw. keep the wiring short and heavy.
I'd bend over backwards to get that machine.
