The two holes feed a channel outside the bushing which absorbs the engine oil thus supplied. When you push out the bushing (can use a socket in conjunction with a bench vise)you will see the channel and can clean it. The plug is located at the rear center of the shaft between the tangs that engage the camshaft. Should be a slotted screw head, but sometimes the slot is broken or smoothed off. Without this plug and a clean center felt wick inside the distributor shaft no oil will reach the front bushing and it will wear pretty quickly even if greased.
I just used some wheel bearing grease on mine. The clearances you note seem large to me and probably will make point gap unreliable when running. I think 0.0005-0.001" probably right, these bushings are normally reamed to fit although I have done mine just inserting them and if they turn reasonably easily leaving it to wear in with oil passages unobstructed of course.
