need help with dtc's

I have a 00 323i and i pulled these codes from it yesterday: P1250, P1189 and P1478 all say Mfr controlled fuel and air metering. Also P0153B: O2 B2 S1 circuit slow response. These were accompanied by a missfire code for every cylinder except #1. Could all this be related to the O2 sensor and if so which sensor is B2 S1? I am going to do the Vanos repair next week as I am having cold idle problems as well as stumbles between 2-3k rpms. Almost forgot i also got a P1421 Mfr controlled aux. emissions controls.
