Certainly the 3" exhaust will make an appreciable difference - perhaps 10 bhp, plus making the car more flexible and nicer to drive. That was my experience with the JT system I had in my old '93. You don't need to re-map the ECU, which will adapt itself, but you might need to re-set base boost (helps if you have a real boost gauge for this).
Having said that, of course if you upgrade the ECU you should buy one that's designed to work with the exhaust you have or plan to have fitted. Buying both as a package may reduce the cost, not necessarily though.
The JT did make the car a bit noisier but it was a nice noise, not tiring either.
Personally would avoid open air intakes unless you are doing something radical with the rest of the engine. There is even discussion here about the advisability of usink K&N filters. I used an ITG filter element, which I replaced with paper a few months bck and I really don't think there's any appreciable difference but olthers may disagree. Either way, air filtration is a Good Idea.
The hooter valve just needs to be working properly for your boost level and the standard one is up to the job (unless/until it fails). But once again, I ebayed a Forge valve and it looks shiny and makes a nice ker-ching sound, well worth the price of entry.
Checking all your turbo hoses, plugs, PCV system and so forth on a regular basis can pay dividends too. The small hoses especially can degrade with heat (like the one to the hooter valve, for instance).
Finally, you already know that depending on what you already have, modest improvements to wheels, tyres and suspension (including bushings) can add to safety and driving pleasure as much as engine tweaks.
