Additionally you can place a picture frame and activate any one of those PDA screenshots on it, thus providing a full map that you can easily glance at, say, while piloting your Cyclops or before exiting your base. That combined with the coordinates available through the F1 key.
Another tip that’s probably been covered RE the scary stuff. I found at one point that when spending lots of time just hanging around an area that terrified me, I would slowly become more and more comfortable just being down there and eventually the terror would subside. I believe this could accurately be described as normalization. :)
