Hydro

Hi, new to the forum with a quick question. I am changing from a double sink to a single sink on a bath/shower remodel. The new sink cabinet will be where the 2.5" vent is. The old sink drains are on the other side of studs. I crudely painted in how this all ties together behind the drywall with photoshop----the vent line goes up through the roof. This drain and vent piping tie in under the house to a 3" ABS waste line. My questions are:
1. Can I just tee into the vent line for the new sink drain?
2. If so, should I cap the old sink drain lines when I removed the peatraps, or put a coupling in and keep everything tied in?
3. For the water, can I just plumb over from the adjacent copper piping rather tieing in directly below under the house. I have decent water pressure, and don't think I'd lose all that much adding the elbows in, but input welcome. If I'm running over from the old piping, it would probably be easier if the old drain lines were cut and capped and out of the way.
Thanks,
RICK
