A walkthrough highlighting items?

Hello! I would appreciate it if anybody could tell me of a walkthrough/guide for the remake that makes makes a point to specify items. I Played the game before and lost my Save and therefore i have to collect my materia, weapons and so all again and would appreciate having a guide that tells of the items along the campain but also side stuff like i distinctly remember a item starting with G that relates to the limit bar. Sorry for any mispellings, English isnt my first language and my auto correct is acting up.
