What to include on my resume?

After working at the same job for 13 years, the company has closed. I haven't done a resume for years. I don't know how to include some things or what to include.

I started community college a few years ago and never finished. Do I include this? I only went for one semester.

I worked for the same place at two different times. Do I list it once or twice?

How far back should I go? I was told only 10 years. But that would only be my last job. And my last job wasn't very impressive. My boss always told us we could be replaced with trained monkeys. The sad thing was it probably could be done. But the pay was good!

I need help please!
