Why would you want to waste money replacing O2 sensors, when you've read the codes and there is clearly a fault with the ETM.......ETM-91A7?!
My P1 V70R had exactly the same symptoms. I'm not saying that I'm diagnosing it, just by looking at your fault code list...I'm just going with the facts and my experience, knowledge and along with what I see on your fault code list!
If you were a garage and you said to me you were going to start by replacing the O2 sensors, I'd be deeply concerned and probably drive away, taking my Volvo with me!
From experience, O2 sensors generally become lazy with age and less responsive. They can last 200k if the cars not had too hard a life, but generally last 100k before they really should be replaced.
As Jamesy says, you need to FIRST clear all the fault codes. Start car and check charging voltage is above 13.5v (under load) and then drive the car for about 50 miles with at least 3 drive cycles (ie switch off and restart). Then reread the car.
I would also select 'live data' and actually see what the O2 sensor voltage's are and that they are within spec.
Granted, replacing the O2 sensors will undoubtedly improve throttle response and idle but O2 sensors won't cause the car to cut out.
Knowing what I know and seeing what you've showed us, I'd be more concerned about the ETM and this would be the first thing on my list.
To answer your question, there are places you can have it refurbished and these guys are probably the best in the UK......

Turn around is generally 3 days and come with a lifetime warranty! I've used them for a dash pod on an Audi TT and they saved me a cool £728!!
Alternatively, a trip to your Dealer will see the ETM software updated first followed by a road test and monitor live readings. If that doesn't work, then a new ETM and software reload will solve the problem and that will cost you £300.
My guess is your ABS sensor fault will return and you may as well get them to replace that too while it's in. From memory, any ABS sensor fault will automatically disable the TRACS, ABS and any DSTC system you have and they are pretty crucial with the cold, wet weather now on us.
