Best way to purchase park tickets for timeshare people??

[Dragonlady]

We have booked a trip through RCI at Old Key West for June 1-8. Since this is a timeshare reservation using points, what is the best way to buy park tickets? We called the 1-800 number to ask about tix and dining (I think it's the same number DVC people use) and the price they quoted was the same as buying tix and dining from the Disney website, no discount. I thought you usually get a discount on tix and/or dining if you book a whole package together but maybe I'm mistaken, or maybe this isn't true for timeshares. In the past we've booked through AAA so maybe that's where the discount comes from. Anyway, we usually do the regular dining plan, which I believe has to be booked through the DVC/RCI folks, but is there a better (cheaper!) way to purchase park tix? I think I read somewhere on one of the SR Disney forums that it's better to purchase tix through the local Disney Store?? (But I would think the price would be the same). And beyond that, is there a way to "link" our park tix to the rest of our reservations so everything is linked on our Key to the World cards? And even further beyond that, we'll probably add a couple of extra days prior to June 1 at a value resort so I wonder if all that can be linked as well?? (whew!)

This is our first trip using our RCI timeshare. We're veterans at Disney planning but newbies on the timeshare end of things!

Thanks much for any input!
