You might want to tell us more about the car and its maintenance history.
And some idea of budget.
The answer might involve prioritization, at least is does for my projects.

It was suggested to me to check / release the preload on the front flex plate

it orginally was placed in storage for a few years, the last owner bought it at an auction, drained and replaced all the fluids, replaced fuel components, it has a little over 36k miles on it, well i just bought the water pump kit so I have like a 1-5k budget to make sure the car is ready to drive without problems.

if you are seeking info .
First read the FAQ at the top of the page, it will take a while but after your done you will be more informed and better equipped to proceed at maintaining your new car.
Simply asking questions will only give you part of what you really need to know, in fact you might not understand the answers you receive, Good luck with your new ride.
Oh and a few pictures would be a good thing and more info on the car would also help, this lets others see things that an untrained eye might miss

Change all the seals that you can get to (both camshafts, crankshaft). change the seals and O-Rings on the oil pump. Get rid of the old TB tensioner and replace it with a PorKensioner.
That's what I'm doing right now as a winter projekt on my 92 GTS.
Check the thrust bearing wear (should be ok @36k). Release any pressure from the flexplate and prevent future movement with an additional clamp from www.928srus.com

The current conventional wisdom is to replace the timing belt and water pump as a matter of course. However, recently there have been a lot of problems with new and rebuilt water pumps failing early in their life (impeller slips on shaft, hitting block, damaging the block and seizing) My thinking at the moment is that if you have a water pump that has been working for a few thousands miles it is safer to stick with it than replace it. People are working on better water pumps and I hope something will be available before I really need one.
Also, some of the belts on the market right now have a tendancy to strech in the first few thousand miles. So you thave three options on the belt: stick with your old one, replace it and watch tension like a hawk for the first few thousand miles, or replace the belt and put in a porkensioner. I recommend the third option.

Better the devil you know...
If you have to replace the WP, ONLY install one with a plastic impeller. The rebuilt WPs with metal impellers are not to be trusted...

You might also want to check the distributors & rotors, many times after sitting for years they will develop oxidation on the terminals. They can be cleaned with a good electronics contact cleaner and a pencil eraser. Also inspect the caps for cracks. Replace if necessary.
X2 on the Porkensioner.
Good luck with your projects, and welcome to the forum.
