you dont need to change any other parts really. It is a direct bolt on turbo (either 16g). It all depends on how much boost you want to run also. I have heard the stock headgasket is good til about 20psi. And if you are going to run more boost you should get a fuel pump upgrade, walbro 190 is good, and also do the fuel pump rewire. Info on that is on vfaq.com. Most places have a turbo swap kit which comes with all the crush washers and gaskets. I know Slowboy has one and I dont see why anyplace else wouldnt have one either. But again as for swapping your 14b for a 16g all the lines will switch over and it IS a DIRECT BOLT-ON turbo.
