Not sure what advice you were looking for in particular. I see that you are an extract brewer, and plan to steep some Crystal-40 for some color. Are you doing full boils? or boiling half the volume and adding water to meet your 5-gallon batch goal?
Also, these ingredients, are they part of a kit, or did you just grab them with a plan to use them to formulate a recipe? Just curious if you already have a hop schedule in mind, etc.
That being said, if I could only use those incredients, I might try something like this...

At least that is a start for you. The Sterling hop is not my usual choice for an American IPA, but I can see it having a supporting role with the Cascades. I've done some IPA's with Liberty & Mt.Hood, which are of nobel hop origin like Sterling, so I can see where it might work well.
Not sure how high Alpha Acid your Summit hops are... in Beersmith, they are very high, so you don't need much to get your IBU's up there.
My loose rule of thumb on IPA's are about 2 oz of hops in the kettle, and 2-6 oz as dry-hops. The above is 3 and 3 ...
Anyways, hope that gives you some ideas for a start. Wish I could be of more help ...
