A2A. I don't know about Physics specifically, but in general, your GPA and letter of recommendations are most important. Research papers can add to application.
I was in engineering, so did not have to take subject GRE, so don't know how much the physics subject GRE matters. But, the regular GRE does not matter much unless the score is low. Not many universities will admit you based on just a perfect GRE score.
I like to blog about various topics ranging from education in IITs to social issues in India and US. All opinions and views presented here are my own and not of my employer.
