Not sure what you mean by the plug "looking like its getting hot" (is it melting, or turning brownish from heat?), but an issue I have had with some bulbs in the past, mostly halogen bulbs, is that if you touch them with your bare fingers, the oil from your skin gets on the bulb, heating it up, and it pops after a short while. I have even seen some bulbs that have an icon on the back of the package saying don't touch the bulb with bare hands.
Again, not sure if there is another issue going on there, but if you are replacing the bulb constantly anyway, you could see if you put the bulb in using a paper towel over your hands, or wearing some sort of gloves to shield the bulb from skin oils, it may help.
Aside from that, I will defer the question to someone more knowledgeable with the 01 and electrical issues.
