I'm not sure what Amod_Log is, but the rest of the folders you mentioned go in the main FSXBA Hornet folder, alongside the aircraft.cfg.
If you don't want all the textures, you can remove both the folders and relevant entries from the aircraft.cfg; however, they will no longer be shown in multiplayer should someone else use it (instead it'll be substituted)
It may be worth noting that textures can fallback to other texture folders, so if you remove one, it may break other textures. An example of this is the default Acceleration Hornet's Blue Angels #1 texture folder -- it contains textures common to all repaints, and if you remove it, the other repaints won't show properly.
