It's been while since I messed with the emissions stuff, so I can't recall details, but from memory there should be a valve where the plugged "T" hose is. The plugged part has a hose that runs to a hole in the airbox, I think. See if there's like a 3/4" hole on the airbox that's plugged now.
You'll probably be able to find more info by looking for "kleen air mod", "evap delete", "pair valve delete", etc. I'm sure there's a youtube video with somebody removing it that you could just do in reverse.
I don't remember if I plugged a barb in the gas tank, but I'm pretty sure I had put a vaccum cap on the carbs.
That said, I like the idea of cleaning up the top-end by removing this stuff, so I would just leave it as is, or get block off plates for a nicer look.
