GP1 and maybe GP4 should be your power layers. I usually get a GP1 and GP2 for them. Anything that starts with A is an aperture list, there should be one (usually identical) for every Gxx file. GxO is overlay, ie. silk screen. So, GTO is Gerber Top Overlay, GBO is Gerber Bottom Overlay. GTP and GBP are paste masks, ands your PCB vendor won't have much use for these files, as they don't do assembly. GTS and GBS are the solder masks. The filename.DRL file is generally the EIA-format Excellon drill file, which few PCB houses want. The filename.TXT should be the ASCII-format drill file, which Adv. Circuits and others are more familiar with. You may have added a .txt file of your own somewhere. GD1 is the drill DRAWING, with symbols drawn on the hole locations, Adv. Circuits likes this as a cross-check against the gerber files. GG1 is drill GUIDE, something like a pad master, Adv. Circuits doesn't want this file. DRR is the drill report, they need this to know what drill sizes to use. I think I've identified all your files.
