Just a couple thoughts from someone who has been there. I'm 6'9" and when I was your age I weighed maybe 205. Painfully skinny and weak. I'm 43 now and around 265 now after having lifted for a couple of years. Still nowhere near as big and strong I want to be, but I have a few more decades to get there.
Do yourself a favor and go re-read what Cthulhu wrote. At 220, you need thickness and that's the way to do it. Big, compound movements. And eat. Now go eat again. You're lucky, you have a lot of time ahead of you.
Educate yourself as to form and find someone who knows their shit who can help you critique your movements. I make no special allowances for my height. Yeah, my legs, torso, and arms are longer than anyone else, but they're in the same proportions as a 5'11" guy. So I just lift the same as anyone else. No excuses or rationalizations. I use the same guidelines for foot spacing on deads and squats and so on.
You probably have a hell of a long stroke on your lifts (my bench stroke is 26 inches) but don't think of it as a negative. I make it a positive by embracing the fact that I spend more TUT (time under tension) as a result of simply having to take more time to move the weight further. More TUT, better results in the long run. And that's what it is, a long process. So be patient and do the right things and it will pay off.
Just be sure to have a complete program and don't do what I did by over-emphasizing the Bench Press in the beginning. I fell into that trap but am climbing out of it. My numbers are way out of whack as my 1-rep max in the bench is 359, but only 405 in the deadlift and a relatively paltry 343 on the squat. That's not a result of being tall, it's a result of being a dumbass. If you do it right from the start, you'll be in great shape.
Train hard. Train smart. Eat. Rest. And enjoy the changes you make to your body!
