Spring maintenance

[tcom]

Ok, it's just starting to warm up here in Missouri and I need some advise on what to do for my baby to freshen her up. It's a 98GT Convertable 5-speed. It has just over 90K miles. I have added a T/A and Pullies. I also did a Flowmaster cat-Back kit.

I know I should change the spark plugs soon.
I did it last at 50k I think.
What Kind? Something cheap but good. I hear Autolite kicked around on here a few times.

I change my oil every 3000 with Mibil 1 Full Syn 5W-30 (Blue cap bottle).

What else would be good?
Tranny fluid? What kind?
Rear Diff fluid?
injector cleaner? (Gas treatement)?

I wax it about 3 times per year with Meguires Gold Glass.
I have some 3M top protectant too.

Any other ideas?

If you're not going to run a power adder,then a brand name set of platinum tipped plugs are a good way to go. Then you won't have to worry about them for at least 75,000 miles. Don't bother with the rear end fluid unless you change the gears. Maybe change the fuel filter too. Coolant should be replaced if it hasn't been since new.
