Break in and other questions!

Audiphils,

I can hardly contain my excitement; after ordering and waiting for 3 months,
my new A4 1.8T is here!!!!!  With that in mind, I had questions that I was
hopping to get answered by the "Pros" out there (YOU GUYS!)  Here they go:

1.  I have heard of the break in period for new cars.  I have never owned a
new car, and for that matter a turbo car.  How should I break in my new car
(drive only 55 mph for the first 1000 miles is what I read on some web
page....)

2.  As far as gas goes, I have always just put in regular gas and gone with
it....What should I do with a turbo in the car?  With Audis in general?

3.  This is my first car with a manual transmission, what should I do to
prolong its life?  What causes a Clutch to burn out?

4.  Upgrades:  I have been surfing the web for hours....I think I want to
chip my car, but WHICH ONE?  I have checked numerous sites (Audi zone and
a4.org as start points), but none have given me that magical insight that
has crystallized the path to choose!  HELP!

5.  Rims and wheels:  Do 18 inchers fit in the wells?  Can't find a straight
answer...  What are the detractors to having big rims and small tires?

6.  Stereo; as far as money goes, which is a better investment:  new
speakers for the car or aftermarket amp to power existing speakers and a
subwoofer?

Sorry for such a long email!  If you know of websites  I could go to find
some of this info, it would be great too!  I have been online for 10 hours
since I found out my car arrived, but haven't been able to find all the info
I have wanted/needed!  Thank you for all your time and responses!  This list
rocks!!!!
