The page for Rebirth PSP has been updated to v0.2 as many more artes and items are now english, as well as cooking ingredients.

I have also found the locations for weapons, armor, and special equips altho they are not english yet. However i have not found accessories, cooking, or gear effects yet. I still didn't touch titles, maybe next time. Somehow the options menu eludes me as well, even tho i found it in Reve unitia and etrian mystery dungeon 2, hmmm...
