I'd go with something 8-8.5' with a rating of 2-6oz. This will handle a wide range of baits.
65 lb. will do, but one birdsnest and SNAP, go with 80 as a minimum.
Use your thumb to stop the lure, do not engage while line is going out...
When trolling, assuming your using a rod holder, set the drag so line will go out but not too easily, turn 'clicker' on. If you don't have a clicker, either hold the rod or keep a close eye on it.
Some anglers use barbless hooks, better for the fish, safer for you...all a matter of choice.
In dirty water, or in low light, do a f-8 or L-turn on every cast, otherwise always watch for follows and do a f-8/L when you see one. Or do one every cast and you WILL catch more Muskies.
