Cats or O2 Sensors need replacing?

EML light came on so had the codes read and the following appeared -

P0173 Fuel Trim (Bank 2) Intermittant
P0171 System Too Lean (Bank1)Historic
P0420 Catalyst System Efficincy below Threshold (Bank 1) Pending

Mechanic thinks it may need anew cat or could be just and oxygen sensor, any ideas chaps? RRS SUPERCHARGED, 22 INCH ALLOYS, JAVA BLACK, FULLY COLOUR CODED

Is the lambda sensor easily accessible to change or will I need to visit my local stealer?

Also does anyone have the correct part number for a s/c lambda sensors? RRS SUPERCHARGED, 22 INCH ALLOYS, JAVA BLACK, FULLY COLOUR CODED

Quite agree Andy but often get in 4 cylinder cars with 2 lambda's and the faults are always recorded as bank 1 or 2 2008 G4 RRSport TDV8 current
