well two questions really,
first, there is a little machined section of the fork that is a little larger than the crown race inner diameter, do I a. just jam the crown race on the last 1/8 of an inch or so or b. do i have to face that off?
second, the headset i bought was very cheap and the dust cap does not cover the top bearing. it fits against the steer tube, but the sides do not go down at all. where do i get just a dust cap only preferably under $10? or is there another way to fix this problem? I can post pics tomorrow if that would be more helpful.

Crown races are almost all an interferrence fit on the fork and require a fair bit of force to seat them fully. Crown race setting tools are basically slide hammers.

Post pics for question #2. I have no clue what you are describing but I'm guessing you assembled the headset incorrectly.

So here are pictures of the problem
First a picture of everything the headset came with (I don't know what the two identical large black things are for, but the bearings fit snugly into the headtube, so i assume they are adapters for something else, and will not be used here):
Then a picture of my assembly order (on top only, bottom is fine):
Then a picture of the problem (this is exactly the above collapsed into the tube as far as it will press, please not the three milimeters of space between the headtube and the dust cap):
These are two photos of the part i am blaming and referring to as the dust cap (please correct me if I that is not the right name):
finally here is a picture of the headtube (please note that the angle is a lip and could not be faced down more than about a milimeter let alone the three i would need to make this close):
Hopefully that is more helpful, what am I supposed to do?

It appears that you have an integrated headset frame but bought a semi-integrated headset. Those "identical large black things" are the bearing cups that would be pressed into the oversize headtube of a frame designed for a semi-integrated headset. The bearings would sit deep enough in those cups that the top bearing seat would mate cleanly.
What frame are you working with? Have you consulted with the manfacturer to determine what headset you really need?

Frame Scattante XRL comp frame, and it need an integrated headset. I was kind of worried about that, it was an ebay buy that said integrated, but there are no markings on the box. I will try writing them, but i will probably end up getting another integrated headset, the dust cap does seep to mate cleanly with the bearing cup, so that is probably what it was designed for.
You know that there are different types of integrated headsets? IT's not enough just to buy any old integrated.
Find out (from Performance) what headset that one needs and order the right one. They are not expensive even at MSRP. Not something to guess at on ebay, not a lot of money to be saved.

As Camilo points out, there are many varieties of integrated headsets. Only one style will work with your frame.
Just to be clear, what you have is a SEMI-integrated headset. It is designed to be used with press-in cups. Your frame needs an INTEGRATED headset. That means no cups pressed into the frame. Cane Creek has a page on their site devoted to helping you determine which integrated headset your frame needs. I suggest doing some reading there as well as contacting Performance.
