there are tons of threads about intakes and blow off valves. try a search...factory forced induction is the best place to learn about BOV. I have the stock intake and bov on my car so I can't help you.
I've read reports of a loud whistle at high speeds, allegedly from the rear view mirror. I haven't noticed it on my car - I'm guessing it's because I have roof racks which make a bunch of wind noise when speeding on the freeway.

Actually the passenger side mirror makes a loud wind noise.. Fold it in and goes away.. Weird somtimes it does and others it doesnt probaballycuz of the way the wind is hitting the car from different angles..

Other questions i have no clue

Yeah, the noise is probably from the mirrors. Get some black foam window sealer and stick it between the hinged part of the mirror and teh mirror itself.

Never hear it again.

As far as in intake, most of them require you to either remove the bumper or the fenderwell. It may vary from brand to brand though.

For BOV's, it's kind of a toss up. Most aftermarket are external venting, but they generally have a stronger spring. So they hold boost better, but you may run lean. The stock unit is a recirclating type, and it pipes the air back into the intake after the MAF sensor. I beleave the consensus is that unless you're doing some major power mods or upping the boost, it's almost a waste. Well, if it weren't for the cool psssssshhhh noise you get.

Go Fast Bits also sells a 50/50 one. 1/2 of the air is recirculated, and 1/2 the air is vented to atmosphere. It can also be operated in 100 atmosphere mode.
