I just finished a SN Celebration clone from a kit. Your recipe looks about right. In fact, it is a bit heartier than my kit was. My O.G. was 1.060 and F.G. was 1.015 (a bit low for Celebration). My kit also had about 2 oz. fewer hops

The hop additions look good. I only dry hopped with 1 oz. of Centennial and 1 oz. of Cascade because that is what the kit gave me.

I tasted the beer while I was bottling and it was great. Good luck with this beer and let us know how it turned out.
