10 ounces of Munich isn't really much- are you trying to use some up? If so that's fine, but I wouldn't go out and purchase 10 ounces of it for a recipe like that.
I'm not a citra fan, but I like amarillo and simcoe together so I think it's good. I think +/- 60 IBUs is fine for that IPA, so I wouldn't increase the bittering hops.
I'd dryhop with citra/amarillo/simcoe because I like amarillo and simcoe, but just citra is ok. I'd dryhop for 5-7 days, with 1-3 ounces.
Mash at 152.
