Textbooks to qualify for USAPhO?

[Jim Bob]

What textbook should I get for preparation for f=ma granted I literally know nothing in physics as of now?
I've heard David Morin's "Introduction to Classical Mechanics" is nice as well as "Fundamentals of Physics" by Resnick, Halladay, and Walker.
Is there a textbook which I can use for both f=ma and USAPhO prep? (Like classical physics and calculus/advanced physics in one book)

I've heard David Morin's "Introduction to Classical Mechanics"

is pretty hard for a first reader. Look at Taylor's Classical Mechanics instead. Still, the author recommends to do some intro "freshman physics" before starting with more specialized literature.

For F=ma & USAPhO prep, whatever book you choose, doing a lot of problems is key. I personally like irodov problems in general physics. Here's a list of resources, but these are a bit more on the advanced side for F=ma. For more straightforward, I would just pick halliday resnick that's plenty to work with already.
