A couple points. A lot of the advice you got upthread here is geared towards photography, and I noticed that you said you're going to school for video production. I'm an amateur photographer and former news videographer, so I thought I could help a bit.
I think the Rebel T4i w/ 18-135 STM is a great choice for video production, and it's probably what I would have chosen when I was in college if there was such a thing. Although the 50/1.8 is a great lens for photography, if I was you, I would get the 40mm/2.8 STM that was just announced instead. It's only $200. If you can't afford it now, wait on the second lens and get it later. I think the STM will be much better for your video usage, and you will not miss the extra 10mm or the extra stop of light. Although thin depth of field is great, it is difficult to shoot at and keep focus, especially if you are talking about video.
Preorder those now, because they won't ship right away. I wouldn't bother ordering anything else until you know that stuff is coming. You might decide to cancel your T4i and go for something else before it ships. Order from someplace like B&H or Adorama. I think they get more stock of the new stuff and they deal with it better than Amazon (at least in my experience).
Get a clear or UV filter sized for both of your lenses to protect the front lens element. Worry about effects filters and step up rings later.
Next, check out what kind of gear is available from your school. Fluid-head tripods, microphones, mixing boards, lighting, etc. Only buy what you can't borrow. However, depending on what kind of video production you are doing (documentary/ENG, music videos, short films, etc) I would consider buying an external mic for audio because the on-board mics will not be stellar.
Also, make sure to figure out how you are going to edit your video. The nonlinear editing at my school was so far behind that I had to edit my own video on my own PC, which is tough because there is no tech support and no forgiveness if you blow a project deadline because you chose to use your own gear. Make sure their system can handle the files/formats and that you can get them into their system.
