Using the display function, deselect all layers except vias, leaving
the via layer as the only layer showing. Use the group function and
drag the entire set of vias. Now select the drill size and right-
click the group area. All vias will have the newly selected drill
size. Now select diameter and select the diameter you want. Right-
click again and the vias now have the annular ring AND drill size you
want. Note that if you leave diameter at "auto", you will get the
annular ring that Eagle defaults to. You may have to try several
diameter changes to get the size you want, but this is easy (one
click) to try.

Hope this helps,
