Hi, welcome to the board!
To answer your questions...
1)A full synethic 0w-40 engine oil is best. You can also get away with 2w-50, 2w-40, 0w-30 full syn. oil. Regular car oil is fine, this machine doesnt have a wet clutch so there is nothing to worry about in that respect.
2)Do not shift at all while moving. You have to be at a complete stop and let the engine come down to an idle speed before shifting gears. Also, if you are going to be idleing more then a few seconds, put the machine in neutral. When you idle in gear, the primary clutch keeps spinning, but the secondary doesnt, so this causes excess heat and friction on both the primary and the belt, and can cause the belt to start to glaze, or even "hourglass". Putting it in neutral will allow the secondary to spin, while the machine still isnt moving, so there is no friction rubbing on either the clutches or belt.
3)Usually brown is a ground wire. Does the end not connected to anything? Is there rubber shrink wrap on the end? Does everything work? The orange/white wire is a 12v accessory power wire. It is not used until an accessory like handwarmers or a winch is installed, and that is one of the wires you could tap into to give those accessories power. So that one is normal to be hanging lose.
