I have been looking for headlights online and have pretty much decided on PIAA. Does anyone have any advice as to another bulb that would be better or is PIAA the best out there?

No PIAA is not the best, just the most expensive.
Have a look at this thread-

Since you have an 06 with H7 projectors, you have some good options available for upgrading your bulbs, and they are cheaper then PIAA. Look into Osram Silverstars, Narva Rangepower, Phillips Vision plus, or similar "high efficacy" bulbs.

i've got an 04 and i'd have to say that the piaa's are a tad on the expensive side. but they've lasted longer than the osram silverstars that i had in there.

this is jus my experience.

thanks for the info.

Any recommendations for wiper blades?

Yes- Valeo Ultimate or Bosch Icon blades. They are the "beam type" one-piece blades used as OEM on Mercedes and other high-end cars. Much better performance and durability vs. conventional blades.
The Valeos on my WRX have lasted about 10 months so far with little change in performance, previously I used Bosch Micro Edge which worked well for a short time but had to be replaced after several months.
