Plan on about 8 h 40 min including short breaks. Free-flowing traffic can do it in 6 h 17 min, but towns, trucks and plaza queues usually add time.
One way with FASTag: bus/2-axle truck ₹465, 3-axle ₹530, 4–6 axle ₹735, 7+ axle ₹890 (includes estimates for plazas without published fees).
Yes, plazas charge the same fee in both directions, so the Mysore to Munnar toll is the same ~₹140 for a car. Fuel cost differs only if you fill up at Mysore's state price.
