If you are staying on points, you are exempt from the daily resort parking fee. Doesn't matter who owns those points.
As for other perks & benefits, the color of your
DVC Membership card will determine what you are eligible for:
If it's blue, you are entitled to all discounts and perks that are extended to DVC members.
If it's white, you are only entitled to pool hopping, DVD rentals and access to the TOTWL. No discounts of any kind (shopping, dining, tours,etc).
