Congratulations....... you've picked the best instrument to play !!!
What's your goal ? if it's just to have fun play a few tunes along to records or even to join a covers band, I'd say it's not cheating at all to get a start by using Tabs. After all it's a resource to learn....
Picking out songs by Ear can be really difficult without a good working knowledge of the fretboard to go along with that great sense of pitch !!
OK Boring stuff now but you really really can't ignore scales....... Major, Minor, Pentatonic need to be grasped as they are (usually) the ones of most use. Not only is the knowledhe of these scales really usefull for building basslines and jamming, but they build up your fretboard knowledge and help with ear training. Also they get your hands in shape and build muscle memory and dexterity which you'll need to play some of the more challenging stuff you'll want to have a crack at.....
Unless you want to do session / theatre work (IMHO) reading music isn't essential but still very very worthwhile, I wish i'd bothered my ass earlier in life.... the older you get the harder it seems to be to grasp complicated stuff !!
Good Luck !
