Since you only have the SRT Intake and ECU chip I don't think you'll be able to tune it. Unless you have an AFC like the Apexi Neo or something.
The fuel filter are suppose to last for the "lifetime" of the car accordingly to Lexus. But you can change it if you want but the other thing with that is the fuel filter is located inside the fuel tank.
Are you trying to add a few ponies?

This is the first I have heard for needing o2 sims with S&S headers. Maybe you do on the gs300 but I dont believe you do on the 4. Someone correct me if im wrong. You can pretty much get anyone to install them who is willing to do the job (pita) . Havent heard of any emissions problems with them either.

O2 sensors are not lost when you switch to the S&S so I don't see why sims are needed.
I can think of easily 4 of us locally in CA who have these headers and pass smog clean as a whistle.
