I am planning on a having a large veggie filter that will be fed by a pump
and will then flow back into the main pond. I am now considering a skimmer
and a bottom drain. What kind of pump set would you use? Three smaller
pumps? Can one or more of these functions share a pump?

I'd use one pump for the bottom drain and veggie filter. My setup is
an upflow filter design that pumps into a veggie filter.
