1. The L2007 is quite popular, well priced and works well, but unlike music, you don't want to slam everything in to the limiter, rather use it to catch any overs. You should do most level control through volume automation and put a limiter on each stem, rather than just one on the buss for your full mix.

You could put a limiter on the full mix buss, but if you've done the job properly and mixed stems properly, this shouldn't be needed, but could be used as a precautionary measure.

2. I never chain them up on the full mix buss, but by use one on each stem, as mentioned above.

3. There is currently no loudness range specified in the UK, but this might change with the introduction of EBU R.128 (if it ever comes to the UK). The BBC recommend that your dialogue levels average around PPM 3.5 - 4.5 (I think - you can double check this) - although that is only guidance, not an actual spec that must be adhered to.

3 (did you mean 4?). OMFs only use mono tracks, just make a new stereo track and move the 2 mono clips on to it.
