Sure. The member from whom you rent the reservation will need to contact DVC Member Services to add the DDP to your reservation. When you arrive at the resort, you pay the front desk for the DDP when you check-in. DVC does not accept "pre-payment" for the plan, unlike regular Disney cash reservations.
As far as park tickets, you are on your own. Park tickets are not part of a ticket dining package with DVC reservations. You may use park tickets from any authorized seller, and mix ticket types within your party (some could have APs, some could have daily tickets). Whatever works best for your traveling party.
