What maintence should be done on my new car?

[onefastman]

I purchased a 98 boxster a few months ago with 133,000 miles and have enjoyed every mile put on it (2400). I was planning on dumping it after a few months for another air cooled 911 but this thing is a lot of fun for what I paid so I'm going to keep it.

I now wonder what maintence I should be performing. The only thing I have done so far is change the oil/filter with a synthetic 15w/50 and replace the convertible top motor.

The previous owner:
1. new brake pads
2. New brake rotors
3. New canvas top
4. Repainted rear bumper (backed into something)
5. One wheel bearing
6. Front sway bar (oem parts)
7. 4 tires HTR Z II


So far I have ordered:
1. Oil/filters
2. Magnetic drain plug
3. Cabin air filter
4. Oem engine air filter
5. Fuel Filter
6. Spark Plugs
7. Belts

I have made a long list of other things I will do but my main questions are:
1. Is anything else immediately necessary
2. Am I just throwing money away on a car that is likely to die from one thing or another?

Thanks for the advice!
