BX2230 my first service

Hi:

I'm not a mechanic. Just want to be clear.
I'm not going to take anything apart.
But, have a couple questions.

I will remove the mower deck and perform regular maintenance.
Thanks to Youtube, I should have that deck off in under 60 seconds.

The machine needs;
Engine oil/filter change
NAPA FIL1358 is supposed to fit. Any drawbacks? I like a big filter and I see there is plenty of length space available.

Grease all zerks

I have been given two new fuel filters, why are there two?
And these are low pressure, correct?
Will adding fuel into the filters during install do any good?

Thanks~
