Need Help Identifying and Placing of 2 Small Parts

Hello all,

Recently I replaced the Lightning Connector in my 16GB Iphone 5S. I got everything back together without loosing screws but I seem to have been left with two small parts, one of which I can't identify and the other of which I'm having trouble placing.

One is a sort of triangle thing with a hole in it, it is supposedly a washer that goes up near the rear camera. The other is a rectangular thing with the edges bent and two holes in it.

Most importantly, are these parts important and have I messed up anything reassembling the phone without them?

I've attached the best photos I could get, but I had to take them with a very low quality camera since my iPhone is still out of commission.

Thanks for any help you can give.
