The hub splines are asymetrical so the the cogs will only go on one way, no chance for a SNAFU except lining up the smallest cog.
Use plenty of torque, the cassette needs to be tight, no looseness or movement between cogs.
There is no need for grease on the outside of the freehub or inside of the cassette, it will just collect dust.
