The Error entries in the log is the most important ones, yes. They are the most helpful when troubleshooting.

The other CTD you mentioned, the one where shot, happens to alot of people. I can't remember it happening to me, so it might be driver related or some graphic setting you're playing with. Start by turning on or off the blood setting in the options. If that doesn't help, try different settings with the graphic options, you might get lucky.
