Questions relating to designing PCBs

This is my first time using vias in an Eagle board - so far not so good. The DRC shows the drill size of both vias as an error, but I have no idea how to resolve the problem.

Can someone please point me in the right direction?

I think I figured it out - the DRC rule for min drill size was 24 mil and my via drill size was 23.62205. I just changed the via drill size to 24.62205 and all is good.

Next question - are there set sizes for the via drills? Should I pick a different value?

No, there are not set drill sizes. If a fab house doesn't have that exact size, they will go to the next biggest bit they have. Which you are talking about a fraction of a millimeter..
