A lot of questions for a single post......

1. I'd run some radiator cleaner through there for a few hours, flush it with water, and add the anti-freeze. Save you a few bucks...

2. The time to change fuel filters is right after running some fuel system cleaner through the gas. I use BG44K about once a year......

3. Plug gap.....around .050. Doesn't seem to be critical. I use copper NGKs.... Don't clean the MAFS like that. Get some spray cleaner designed for sensors. Auto Zone sells it.

4. The cabin filter is under the passenger side cowl. Not all cars came with one however.....but the housing is there.

5. Most fluids need to be changed when they start to look dark. P/S fluid should look clear/red.

6. Automatic trans fluid should also look clear/red, and not smell burned. That's not an easy change on these cars. It's silly to put anything other than stock fluids in these cars, unless you're racing. You'll gain nothing except bragging rights.

I always recommend a through cleaning of the engine/transmission as a maintenance procedure. You'll be able to see/find problems easier......

Good luck with all that.....
