Headlight and Aiming

so drove my eg yesterday durring the night time for the first time. pulling out of the garage i already noticed my headlights arnt aimed correctly at all. this was worse when i was driving cuz i couldn't see shit. im some what familiar with the aiming processs ( tape line on wall. move 25 feet back. aim lights 2 inches lower) but even when i pull about 5-10 feet away. there wayy out. gonna dick around with it today but dose the light mounting make a differance or should i just mess with the 2 adjusters on the back. the driver side headlight sits a lil loose and i think its cuz of a bolt in the back that dosnt sit correctly, but not quite shure.
real question is where should i start. should i make shure everythings all secure then begin to try and aim it correctly. or what ?
thanks for the help.
