Guidance on resolving P0134 & P0455 error codes

According to the code decoder:
P0455 - which is large evap leak detected
P0134 - no activity bank 1, sensor 1
I don't believe these are related...are they?
I replaced the fuel filter (new bosh + fittings) about 50 miles prior to getting the above errors, did not get any gas in the interim. I checked the gas cap.
Where is sensor bank1, sensor1 located?
I replaced an o2 sensor about 30K miles ago but I'll have to check my service log to see if this is the same sensor. (could this be related to the famous 'bad junction' issue I've read about?
Also, about 100 miles prior to this event, I got a P1110 code - bypass valve, bypass valve controller, or hoses. I found a leak in one of the vacuum lines and replaced it. Are these related?
Suggestion on what code I should try to resolve first? O2 sensor?
Thanks
John
