A common and simple Thanksgiving centerpiece is a basket of gourds, small pumpkins, and squash. If you're looking for something still easy but more advanced, stick feathers into a medium size pumpkin (like a turkey). Use a wooden skewer to attach a smaller pumpkin to the larger one (as the head) and attach wiggly eyes.
You can buy Thanksgiving decorations at any major retailer such as Stop & Shop, Shaws, HomeGoods, etc. Thanksgiving decorations go on sale a week or so after Halloween.
