E430 Engine Codes

Well I went to Autozone and they were able to do the diagnostics for me - I have the following codes:

P0170 - Fuel compensation value for bank 1 exceeded the specfied range.

P0173 - Fuel compensation value for bank 2 exceeded the specified range.

P0410 - A malfunction exists in the secondary air injection system.

Is anyone familiar with these? Are they a 'dealer only' fix or can I do it myself? What part or parts do I need to check and/or replace? Should I replace my MAFM and/or O2 sensor?
