My 2006 CLK350 is suddenly shaking pretty bad at idle and when driving

I am getting codes P0050, P2237, P0128, P2240, P064D, P0030, P2237, P2240

they all seem to say:
O2 Sensor Positive Current Control Circuit/Open Bank x Sensor x

HO2S Heater Control Circuit (Bank x, Sensor x)

Internal Control Module O2 Sensor Processor Performance Bank 1

Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature)

Has anyone dealt with this before? Does it most likely mean I have to replace O2 sensors? If so, should I replace all at once?

Thanks!

Updating this in case it helps someone in the future

The problem was the thermostat, as indicated by the P0128 code

Replaced the thermostat, car is running fine. It was stuck open and the car was running too cool, didn't reach normal operating temp, which I didn't notice, and the mixture was too rich it seems, causing jitters
