Best way to tackle this job?

I'd rent the pitman puller if you can get one so you don't damage the pitman arm or the boot. I bought one of these.

Yeah there is an AZ pretty close so I don’t mind to drive over there to rent one if it’ll make the job easier. Should I pick up an oil change while I’m there — will the passenger header be easier without the oil filter in the way? I don’t run the 90 oil filter adapter, just screw it straight to the block.
