Studying soil microbial communities

I will sequence DNA and RNA from grassland soils using Illumina HiSeq to see differences in composition and functionality (removing 16S). I will use DNA sequencing as a reference to align RNA. I need to establish the paramenters to do the senquencing, 2x100? 2x140? 2x200? I also need to know the minimum reads per sample I will need to see reliable results... 20M? 45M? 60M?

JGI has been sequencing lots of soils. Why don't you download some of their data and subsample the data to evaluate read # needed

I have lots of strong opinions on how to survey communities, pretty sure some are even correct.
