Fuel leak is likely stemming from the feed lines/rails. More then likely a pulsation dampner failure or a cracked rubber line.
Pull the UIM and take a peek, that one should be obvious.
As far as the headlights go, if the wiring isn't all jacked up - the 30amp fuse under the hood should be providing their power. Check for power at the fuse, if there's nothign coming in, then your problem is before the fuse, if powers coming in, then it has to be after. Can't really perscribe too much until we know which side the problem lies.
