If they are color photo like images then jpegs are the best, you can vary their quality and resolution to keep them small, cropping them to exactly what you see in the layout also helps.
.png are good where you have a transprent background but they are bigger.
If you have vector (drawn lines and shapes + text) design then .pdfs are best, particularly if they are flat color.

Thanks, Peter! I do have some photos w/ transparent background, i.e., I took a picture of a cactus and then "cut it out" of its background, but the final product would not be any larger than the others, i.e., still 2"x2" max. Because of the trans. bkground, should I import that as a png?
A related question - I'm assuming I should optimize all of these photos before importing them, but is that something that perhaps Pages will do of the whole document when it's saved as a PDF?

Actually OSX when it exports/prints to pdf seems to optimise the images but not size wise.
I always go with fixing my own images and not relying on other software to clean up (fingers crossed).
You can maintain transparent backgrounds with both .psd files and .png. The png have to be rgb however, where the .psd files can be whatever you want to make them.

.psd is Photoshop native format.
Jpegs do not have transparency (Alpha channel).
I forgot to mention that if you have Black & White (2 bit) images or even greyscale, they are best in .tiff which can have a compressed format that brings them down to a very small size and can also be colored in software (given a tint).
