Bass==> Board #1 (Tuner, Comp, Muff, EQ/DI) ==> Amp ==> FX Loop Send ==> Board #2 (POG, Chorus, Env Filter) ==>FX Return
Have we cracked it?

I think you'd be better off with a true bypass loop on your first board after the compressor and plugging the second board into that.
Besides Sibob's comment about effects loops expecting a line level signal (such as a rack-mounted compressor or effects unit), many effects loops are parallel, in which case you will get a blend of the signal from the pre-amp and the effects loop. And, your second board is going to be downstream of the DI so you won't be sending the same signal to the PA.
