I guess the only other suggestions I'd make are:

1. Don't spend more than a few minutes looking for a ball. Sure it hurts to lose a ball, but it's only a few dollars and not the end of the world. Besides, if you haven't found it after a few minutes when the rest of your group is helping you, you aren't likely to find the ball. Just move on and focus on the next shot.

2. For the high-handicappers/beginners, the course is not a driving range. If you're having trouble getting to the green (i.e., double par or over), then just pick-up the ball and catch-up to the rest of your group and just putt. I know that I've done this a few times when I started. I realized that I'm not going to be able to fix swing flaws on the course, so there's no need in getting frustrated because the ball isn't going "where I want it to go". I figure I would much rather be courteous and try and maintain speed of play until I get better and can justify taking an extra moment to prepare for a shot going for birdie/eagle, etc.

Hans.
