Take a look at Mads Electronics Smarty Jr. Couple that with a nice set of gauges and you will have a very nice setup. Taking the silencer ring out will not do much of anything but make the turbo louder. A good intake, AFE, S and B are prolly the most popular with guys here, a good 4in exhaust will do plenty but 5in does sound good and a nice tuner will get you a good MPG gain but will not take the place of good driving habits.
 
Wow other than the smarty which has a set price by mads those prices seem a bit high, try posting in the vendors section here an see what you get. Also i prefer a single gauge as they are quicker to read and provide instand feedback where some of tge screens can have a delay for the ecm to update them and dont refect changes as fast. Plus of one fails you can just replace one not the whole thing. Also with stock turbo and smarty jr all you need is a 30-35psi boost gauge, nothing wrong with going with the bigger gauge though.
