Welcome to the club! Just picked the game back up at 37 after a long layoff, haven't played this regularly since high school.
I'd agree with leaving the driver out. Short game, short game, short game. 150 in is where I'm concentrating. I've personally found a very short muni course, 11 bucks a loop, where you only need irons.
I have pretty high ceilings so I hang a sheet in a door way and hit foam balls into it.
YouTube, and the library. I try and read as many golf books as possible... I figure the more info the better...
I'd also suggest getting fitted if possible. I'm very tall, so a proper sized club was a must.
