Help with diagnostic codes
 

I'm having a hard time figuring what went wrong after I replaced the thermostat and a couple of hoses on a 2002 Freelander 2.5.
I had a couple of the brittle vacuum lines crack during disassembly, and obviously when I put them back on, it idled rough. But then I replaced them with intact hoses from the salvage yard,and now I can't even get it to fire up. Cranks but won't start.
It's throwing the following trouble codes, and I don't know what to make of it.
P0175 System too rich Bank 2
P0303 cylinder 3 misfire detected
P1475 leakage diagnostic pump reed switch did not close
P1477 leakage diagnostic pump reed switch clamped tube
P0138 O2 circuit high voltage (bank1, sensor2)
P1451 Evap emission control STS vent control valve circuit
P1472 HO2 Sensor heater control circuit (bank1, sensor2)
P1471 Variable inlet manifold motor short circuit to battery

Please, someone familiar with this, help me out here!
