Question SES codes

I had my car scanned and it is throwing codes for all four O2 sensors. I expected codes for the rear sensors since I don't have them connected. But the heater circuit malfunction code is popping up for the front O2s. My question is do you need to have all of the O2s connected to complete the heater circuit, or did I wire the front sensors wrong when I extended them. Also, would that heater malfunction code effect anything. I think that the car is going into limp around mode, it feels not as strong as before the header install.

List of codes:
P0140-O2 sensor no activity (bank 1 sensor 2)
p0155-O2 sensor heater circuit malfunction (bank 2 sensor 1) *
p0160-O2 sensor no activity (bank 2 sensor 2
p0300-random multiple cylinder misfire detected

Pending:
p0135-O2 sensor heater circuit malfunction (bank 1 sensor 1) *

The car is using the stock tuning right now and will hopefully be tuned this week or next week.
