Is where you will find the answer to your upgrade questions.
Many people are unhappy with this system and solutions
have already been worked out . You are describoing the base system not Hi Fi
Hi Fi has tweeters.
Hi Fi is not that great it falls apart when you turn it up

1. Is every E90 pre-wired for the subs under the seats and the amp in the trunk? If so, I can buy the original subs and an amp from a friend for fairly cheap.

Stereo does not have the amp in the trunk and probably does not have wiring but you can
get an aftermarket harness from Technic these harnesses are included in the Musicar Kits

2. I know that by adding the subs and an amp to drive them, I would be feeling more low end, am I going to feel more clarity and punch overall by this addition if I turn the bass on the head unit down thereby just using the pre-existing speakers for highs and mids???

The existing speakers are cheap and won't handle much power the best solution is aftermarket speakers and amps

3. Should I be considering other amps and subs other than the original OEM's? The fact that they fit under the seats was a big motivation for choosing the OEM's....

Yes. there is stuff that fits but its not the run of the mill pioneer or sony stuff
not many make 4 inch components door speakers that fit or the low profile 8 inch speakers
that go under the seats there are some good ones out there though

4. Is the stereo that I currently have considered the "Hi Fi" version (no tweeters by the mirrors, no subs, and no amp in the trunk)?

You are describing the base stereo
also that system requires a processor to flatten the head output
