1. Do I need to put any lubrication in the inside surface of the
sealing ring on top of the water pump housing?

You can pre-lube it with dishsoap or KY - avoid petrolium based stuff. Same
goes for impeller.
After you run it - the water will wash all away and your final and only lube
will be the water.

2. Do I need to put any gasket-sealant on the gaskets of the water
pump housing?

NO - just make sure all is clean.
