I need help at some place

I just talk with Aerith and she wants me to get some woods. The thing is that, the game is in Japanese, so i’m not sure if I got the three pieces. I’ve read some walktrough, and it says that I need to get some on the way, talk to someone in Loveless sector and to someone who owns a shop. I think I got the ones on the road, after the church, but i’m not sure about the two others…

Can someone tell me exactly to who am I suppose to talk to get all the woods please..

Thanks
