There are conversion kits available, Stan's seems to be the most recognized brand at the moment.
Going back to your current set up, where are you getting the holes? Inside of the tube? Outside of the tube? Snake bite puncture? Repeated flats often point to something not right with your wheel/tire.
If the holes are being made on the outer diameter of the tube, one of the metal threads in your tire casing may be broken and bent slightly outwards, puncturing your tube. Or maybe you have a thorn/piece of glass/staple stuck in your tire that keeps puncturing your tube.
If the holes are inner diameter of the tube, you probably have a spoke nipple poking through your rim tape, which is puncturing your tube.
If you get snake bite flats (two puncture holes pretty close together, you are running tire pressure too low for your weight/riding style. What is happening is when you hit a root/curb, the tire is compressing down to the rim, pinching your tube between the obsticle and the rim. This might also explan your valve stem, if your tire pressure is too low, your tire/tube can slide forward on your rim cutting your valve stem/tube connection on the edge of the valve stem hole in your rim.
