I can help you in two ways, a little bit. I upgraded my seats with a full power leather interior from a wrecked limited. I found the full interior on ebay for $750, and that included both front and back seats. So I have my stock seats I may be willing to sell for the right offer, BUT they are NOT SR5 seats, they are the base buckets w/ no lumbar and little side bolstering, basically they are the same as tacome seats. If you are interested let me know, you would be responsible for all shipping costs. Also, I know you can get aftermarket buckets for reasonable prices, my base seats are very uncomfortable, IMO. Check Performance Products for ideas as I know they sell seats for these trucks.
