2009 bmw 335i sedan w/ MT and ~140k miles

Situation:
car drives horribly (rough acceleration and poor power delivery) and currently have SES / CEL on
I used my bavarian technic cable and my cobb ap to find the following codes which i attached in this post

QUESTIONS:
1. are these codes indicating issues with the primary cats in the dps or the secondary cats or both ?
2. do i need to replace any or all of the o2 sensors as well ?

I decided to go no cat dps rather than going back to stock - want to get all the parts i need first and understand what i need to do

i can use my cobb AP to flash my car to pass emissions (hopefully) but i am trying to figure out if i need to do the o2 sensors in addition to removing my current stock dps w/ the bad cats

my car runs atrocious b/c of this and also primarily b/c it's got 140k and has NEVER been walnut blasted - that's on my to do list as soon as all the tools for the job get to me

Any input ?
Thanks!
