With the idling problem, scan for codes. You will have one or more stored because of the check engine light. If it's Code 41 (too lean), suspect a vacuum leak. I had a problem like yours, it would idle okay for about 10 seconds, rev really low and stumble then pick back up, and then I'd get a check engine light. I had knocked the PCV valve off of its hose by accident.

For the dash lights, try taking the steering column shroud off and wiggling the wire bundle around.

It's a good idea to put hose clamps on the pcv hose, especially the bottom one as they tend to get lose with age. Checking it with a vacuum gauge would also be a good idea.
