I would like to replace my existing single bathroom sink with a double sink. Can i just connect the second sink (under the vanity) to the existing waste line? I'm only concerned about the waste line, I will be running new copper water lines to the second sink?

Normally NO you would need a separate trap, but some Mickey mouse so called plumbing codes may allow the use of tee so one trap may serve both basins.
Also the vent should be with in 2 feet of the trap and the trap with in 2 ft of the fixture

If I put a trap on the second sink and then tie it into the original trap on the exosting sink and then into the existing waste line, keeping it within two feet of the vent?
