+1 to the folks talking flash, as even at f1.4, your tremor will impact the shots. Honestly, in some situations I'd add a flash with a Rogue flashbender on it. In other situations, bump the iso up even higher. I would recommend you rent/hire the tamron, or consider the 6D for a little more money.
I know tripods can be a royal pain to setup and tear down, but I wonder how a mono-pod would work with your tremor. Treat it like a walking stick, set the camera to 2 second self timer, and hold a strap while it takes the actual picture. Either that or one of the basic glidecam setups, with a wireless trigger on your other hand, using live view to frame things.
