Try to get away with as few colors as possible. Each color that is used adds more filesize when it is saved, because it increases the palette.
There are a few file optimizers out there, however, you can get close to the lowest filesize, just using Photoshop.

Actually palletes only have meaning in 8 bit or lower images. The color depth determines how much information it takes to represent a single pixel of data.
Never use 32 bit unless you want transparencies, because a 32 bit image is still only using 24 bits of color information. The extra 8 bits are for an "alpha" channel for other stuff.
