If your current soffit lighting is great, I don't see any reason to change to pendants, as I doubt the light quality would change and the look won't be that striking because of the short drop. To improve the quality of lighting at a mirror you would be better off with side-lighting. Overhead light is supposed to be less flattering and casts shadows that make it harder to apply makeup, etc.

OP, Before you replace just the sink, consider the cost of replacing the entire unit. I have a very similar vanity/ top / sink that came from Lowe's and was not terribly expensive ($350). The one that you have isn't in bad shape, but if you wanted to change styles, or if it was otherwise damaged this would be an opportunity to swap it out. BTW: The bowl is probably sealed to the granite with silicone sealant - you will have to cut it from the top after removing the bolts. You don't use plumbers putty on granite. Also, the top is pretty much permanently attached to the base. I was going to take the top off mine when I brought it home to make the installation easier and lighter... I think it was epoxied on to the sink base. I do agree, however, that the sink is probably fine. If the crack gets bigger or leaks, deal with it then.

to me, this cabinet looks like something that could have been in a home of the vintage of yours - certainly more than one with beveled glass and no frame would! The little knob does it. I have two of this exact med cab and we love it. It is so tall that we can put the first shelf above the Oral B toothbrush handle in its charger and still have lots of storage space. We have the large one.

Please post pictures so, we can see what you have in mind.
