Do you have to use plumbers putty when installing a new drain?
The putty will help the upper part of the drain assembly seal against the sink drain opening. If you do not have plumber’s putty or cannot use it on your type of sink, then you can use silicone or even the foam or rubber gasket that comes with some pop-up assemblies.
Does a kitchen sink drain need to be vented?

Why is the pipe under my sink leaking?
Arguably the most common reason you’ll find water beneath your sink is that your drain has a leak in it. Shifting plumbing lines, worn-out connections, or even pipe corrosion could cause fractures in the plumbing lines beneath your sink, which cause water that flows down your drain to slowly and steadily leak out.
