basin waste fittings

[sscomp]

I have the job of fitting a new basin where the old one was and need some advise on the tap with lever for the basin waste plug pop up.
1) will the rotating ball that the bar lever goes through be water tight and do I need to put some silicon grease in it?
2) the basin drain plug has 2 rubber seals is that waterproof or shall I put some paste on them as well?

3( where the top plug screws in to the bottom waste part do you put anything on the threads?

Fit a basin mate then there will be no leaks. B&Q sell them but not sure what they call them. Google this part.
