If you're staying on points, no, you can't get the free dining. That's a promotion that Disney uses to fill resort rooms during the slower fall season. You'd need to purchase a package including a rack rate resort reservation and tickets to get free dining. Whoops, and I didn't notice your dates. Free dining is only offered in August and September.
As a member, you can purchase the dining plan at its regular price, just contact Member Services to add it to your reservation.
The only ticket discount we get is $100 off annual passes. You can get those through the member site, or buy them when you get to WDW.
