Hello I just got a 97 del sol si, and I would like to do a tuneup myself. I can do the following myself, but what am i missing??

- oil change
- transmission fluid change
-spark plugs
-NGK blue plug wires.
-air filter.

please add anything that is critical and need to change. I want to take care of the maintenance part of the car 1st, then I'll drop it with a front lip. simple and clean. thank you.
