I shoot with a T3i, usually around the Zoo, maybe walking around town or the forest preserve, looking to someday go beyond serious hobby.
I wouldn't miss what you have in the not sure category, but, if it was me, I'd keep the 40mm/2.8 and 18-55.
The 40/2.8 because it is small and works with FF. It is deceptively small and can make your DSLR look smaller than it is. A few times I forget that I actually packed it in my camera bag because it gets lost with the filters, spare batteries, and other stuff.
The 18-55 because it is so cheap, you won't get much for it, but, it is the smallest standard zoom you can get for crop sensor. Mine is a sacrificial lens I leave on my old Rebel. I don't really care what happens to that old REbel and 18-55 and so ironically that setup gets a lot of use in interesting places as I loan it out a lot.
