Hi, welcome to the forums and congratulations on your new purchase.
If you are going to do some modifications, using the search tool can bring up lots of good information.
HERE is some info on painting the calipers.
As for the intake you have two options:
K&N make a 57i pod filter setup, which may give slightly more power, but suffers from lack of heat shielding. It does give an excellent induction roar.
Alternatively, K&N (and some other brands) made a replacement drop-in panel filter. This will also allow for increase airflow, however, it retains the original airbox setup.
With either option, do a search on lower airbox / intake resonator removal, which will also allow you to route cold air feeds up to your new panel filter / pod filter.
