So, you have Chest/Legs Monday.
Bi's/Tri's Legs Wednesday.
Chest/Abs/Back/Shoulder/Legs Friday.

Your aim is to work off some gut. OK!

First thing that strikes me is that your working lots of muscle groups at the same time, to much for me and my liking.
Your cardio or warmup is a good basis to work from though.

Every man will have there own way of training, what works for me may not work for you. My advice would be.

Monday work Chest&Bi's then hit your abs.
Wed work Shoulders & Legs hit your abs again.
Friday work Back/Tri's, Hammer your Abs yet again.

Idealy after working a targeted muscle group, you should rest that muscle group for a week.
Targeting & training your muscles in groups as sugested above will allow your muscles a week to recover, which gives them ample rest & recovery time.
Abs are unique in that they need less time to recover, it is possible to work them every other day.

Like I said above everyone will have their own experience of what works & what doesnt work for them. So dont take the above as gospel.

Hope that helps, if you do change to the above, id be interested to know how you progress with it.
