As-Salamu 'Alaykum brother
no the people of Ahlus Sunnah (salafi) don't take literal meaning of every ayah of the Qur'aan. We understand it how the Messenger of Allah (sal-allahu 'alayhi wa salam) has taught us and how the Salaf understood it. Just because we believe and take Sifaat of Allah upon their dahir (apparent) meaning, which is what we suppose to do as explained by the Sunnah and athar of the Salaf, doesn't mean we do the same for all other matters. Simple guideline is that we believe in the Qur'aan, the Saheeh Sunnah and understand them how the Salaf understood it.
Wallahu A'lam
who do salafis take as an authentic muffasir? is there any salafi accepted version of tafsir available on the net?
