If you check the dip stick and it smells like gasoline, drain the oil and change it before any damage is done. Gasoline not only does not lubricate but it washers the oil from the bearings and can cause catastrophic damage.
Find your fuel leak first. None of the things mentioned, like fuel regulator, MAF, etc WILL cause fuel to leak on to the ground. Those items will affect the fuel ratio to the cylinders but not cause a leak to the ground. I suspect that you have an EXTERNAL leak in one of the fuel lines that is causing fuel to leak. This leak may also be causing air to enter the system and affect your air/fuel ratio. If you find and fix the external fuel leak, your other symptoms may disappear.
DO NOT over think all of the codes showing up. I suspect the external fuel leak is the main cause of your problems.
