If I install a front mount intercooler?

Agree. There is a potential amount of power that our turbos...
can produce. There are many factors that affect this, one of which is ambient temperature. The second IC of the 225 and the larger size of the FMIC allow the intake air to be cooled more then it would be otherwise. You are simply giving the turbo a chance to produce its potential HP-- you're not pushing it harder. And you can bet that there is a wide margin of error built into the engine as well, so it can handle far in excess of the few extra HP the FMIC might allow you.

you are correct 'cept for one thing...Heat is not an enemy of the turbo per se
as much as it is excessive heat.
Heat is what makes the turbo function, without it, the whole process doesn't really work.
Excessive heat on the other hand is the enemy of turbo's but no amount of intercooling will fix that problem. This is more a function of the ineffeciency of the turbo running above and beyond its capabilities.

i was under the impression that the turbo spools to a maximum rpm regardless of temp...
it's how cold/dense that air is reaching the engine that the intercooler effects. if more dense air reaches the engine because the intercooler allows more of the turbo's potential to be realized, the only thing i can see is the possibility of the engine being forced to work too hard. but from what i've read/heard, the audi 1.8T is a solid block capable of much more power.

Not sure that's 100% correct. The intercooled air does not go to the turbo.
It is fed to the intake manifold where the cooler denser air can pack in more fuel molecules.
Once combustion occurs the spend exhaust gas then spools up the turbo which pumps the compressed (hot) air back into the intercooler cycle.
Correct?
