I thought for a few minutes and didn't come up with much in the way of "if you're not a nerd, at least do these things."

One resource is AARP:

http://bulletin.aarp.org/yourmoney/scamalert/articles/

Not focused exclusively on what you're looking for, but there are some things in there.

Unless you do find the type of resource you're looking for, you may have to do the research and distill it yourself. You could create a page presenting that distillation.
