Here's a nice, big image of the mad tea party, so all the stuff is visible. (although the hatter chair is kind of cut off on the left side).
Rare items: in the chair gacha the table is rare and in the table setting gacha the tree is rare. The tree includes three hanging centerpieces. Each centerpiece is it's own piece of mesh, as it the tree, so they can be easily unlinked and re-positioned.
