Replying to Setting up a DSLR filming rig

I'm looking to set up my T3i for some filming this winter. I've been testing out a sigma 10-24mm and think I'll go with that over the tokina 11-16mm. I've got a battery grip, going to be setting it up with magic lantern and have DSLR RC on my phone, just trying to find a Bluetooth adapter that's compatible with Canon. If I cant find that Chainfire has an android controller that runs off a USB connection.
If all goes well I'm going to buy a glidecam hd 4000 off here.
What else should I be looking at for a set up? A matte box with some ND filters? which ones work best?
