I'd probably lower that a little in regards to the vault and the library.
130 for the library is fine. You can do the library in full augmented ironworks and it's not a problem. the only class that might want to change gear a bit is the tanks cos the def boost on the 58 gear is a big jump. but the rest of the stats aren't much different between the i142 level 58 stuff and the i130 augmented iron works. you wouldn't really notice the difference between using like augmented iron works bow and the level 58 birch bow for example.
its why so many people went all the way to 60 in aug ironworks / dreadwrym because it wasn't worth worrying about gear till 60.. you level so fast anyway the time you spend getting gear you could have levelled past it anyway.
