Okay so yesterday i started the quest "Proving Honor" for the Companions. I know that ones you reach the room with the fragment that there is also a word wall, my question is this. Can i read the word on that wall already even though i have not started with the main quest yet, and as such have not met any dragons and such? Although i did talk to Jarl Balgruuf and Farengar. (Now you may ask how i know of the word wall in that quest...well i hat a previous warrior with which i hat started that quest and i reached the end room of that quest. But i made the stupid mistake of deleting the savegames before backing them up.

)
My second question concerns the armor that several members of The Companions are wearing. Can it be bought or found some where, also is it any good and can it be upgraded by smithing? And the armor i mean is seen on the below picture.
