My Ride: 2000 stahlgrau 323it
Four engine codes on my newly purchased 323it

I plugged in my code reader today and found four codes, which all seem to relate to the same area of the engine. The codes are:

P0305 - engine misfire cylinder 5
P0150 - 02 Sensor Cirucuit Bank 2 Sensor 1
P1421 - Secondary Air System Bank 2
P0154 - O2 Sensor Circuit No Activity Detected Bank 2 Sensor 1

I have read that Bank 2 is cylinders 4-6, which obviously contains the misfiring cylinder #5. From my limited understanding it seems that all four codes are being thrown in the same part of the engine, possibly even due to the same failure. Moving forward, is there a best route to take testing (and how do I test? I have a multimeter and a desire to learn... do I need specialty tools?) to diagnose what, specifically, needs to be cleaned/fixed/replaced?

Thanks for your time. First time working on this engine, don't know much about it yet.
