For starters, remove the tape and the putty.
The swivel gets tightened first, and then the other nuts.
But really, anytime you replace a sink basin, you are better off buying a new p-trap with new trap adapter, and installing them where they should be.
I would normally pick up a PVC p-trap with ABS trap adapter.
Maker sure on the new p-trap, that you cut it to the proper length.
I cut the trap arm flush with the wallboard.
You don't want it going so far in that it blocks flow at the fitting inside the wall.
