Looking to upgrade from my T3i and I have a few questions.

You'll lose the T3i's video zoom feature, if that's something you care about.

I have only tried it a few times, but for sure would not miss it if I changed cameras. If you actually use it while recording, you ruin your video.

I would hesitate to get the 28-135mm. 28 is not wide at all. The 11-16 is ultra-wide, so you'll still be missing an important chunk of focal length, and you'll constantly be fiddling around swapping lenses. If you're looking for a quality replacement for the kit lens, with more range, and you're fine with the aperture on the 18-55mm, the 15-85mm is the lens to look at. For a wider aperture, look for the Canon 17-55mm IS, or look for a Tamron 17-50mm (non VC) to save a few hundred.

There is a used 17-55 for sale here in the forum:
