Just remove the EGR and be sure to get a tune. The car will not run optimally with the changes you are making but it will not "throw the whole car off". O2 position will also be negligible. It's not like the sensors are being moved to the tailpipe.
I would suggest maybe just saving some money and installing these yourself unless you just want someone else to do it. If that's the case, you might want to get a second opinion/price from a reputable local shop.
Not sure if it will be needed but check to make sure o2 wire extensions will or will not be required so you can plug everything in.
