T3i, 18-55mm, 55-250mm: Will This Package Be Good For Me?

Thank you for the suggestions of different cameras. I looked at both cameras and prefer the SX50 due to the articulating lcd screen. This is a MUST for me. I am somewhat physically limited, and can't twist around and upside down to get the shots I want, also lightweight is very good due to the same reason. I realize dslrs are not all that lightweight, but most of the time, I set up my F717 on a tripod to maximize the quality of the pic, so I just assumed I would do the same with the t3i. I didn't make the weight or lcd a factor in my original post because it wasn't relevant. But if I go looking at other cameras, a fixed back lcd is out. The SX50 looks very interesting, and is definitely something I will consider. Thank you very much!
