DV will be a must as they tend to pack in once you start running more boost (have a look at APR's new type) if you are going to do the intercooler piping then have a look at Autobahn88 Silicone pipes as they are as good has Samco's and about half the price (Just fitted them my self).
I would not bother with intake as the stock unit works much better than an open filter and you will loose power rather than gain as it will be sucking in hot air and loose the Ram air effect that the current system provides.
