Sounds like you have it down. It is kinda hard to understand all of your questions.

Yes some grease should help. Use the search function on this site and you will find service manuals, and reference others works. Careful with the Harmonic Balancer bolt it is easy to snap the head off if you torque it too much.

The new key should be in the groove snug, if its sloppy it is not the right size.

Remove all the old bits and pieces, put new key in slot on crank, slip balancer nose over crank and key and use your installer to put it on. Depending on how tight it fits, I will warm the balancer up to expand it and help it go on easier.
