As far as drill hole size goes, Mikes Workshop (http://www.mikesworkshop.com/blades.htm) shows the minimum drill bit size that can be used for each saw blade. Then on the page for drill bits, shows the size of each of the bits. These pages show that a no.71 bit can be used on a 2/0 blade, but most of the time I just use a no.68 bit which is 1/32".
