What level of physics have you studied already? engineering level? physics undergraduate?

comment Self Teaching QFT
I found the whole book hopelessly deluded in its purpose. To learn QFT, you have to start with a good grasp of classical mechanics, electromagnetism, relativity, quantum mechanics. it would take at least a year of self-study to get through just one of these while holding down a job at the same time. The book you've recommended is likely to be of use to a good physics undergraduate only.

comment Relativistic factor between coordinate acceleration and proper acceleration
@diffeomorphism you're right, that last comment is badly worded, but I can now see what the issue is. I've updated my answer to make clear what's meant by the "proper acceleration" in the formula you're trying to derive.

comment Euclidean geometry in non-inertial frame
I find your other answer far clearer, and maybe you should focus on tweaking it, rather than this one which is too difficult for a beginner to take in on first reading.
