Well I just downloaded beersmith and ran this recipe through it.
Everything showed to be in line with an American wheat with the exception of the color which was 7.5 SRM so slightly darker than what it should be due to the extract which I can live with.
The IBU's were a little on the high side but still in the green as well as the ABV but again still acceptable.
I think my hop schedule will be 1 oz. UK Goldings for 60 min. with 1/2 oz. Cascade additions at 10 and 5 minutes at the end of the boil to keep the IBU's in check and hopefully get some good citrus aroma from the cascades to complement the orange zest and coriander.
I dunno how this will all turnout but I'm doing it tomorrow so wish me luck as this will be the first recipe I've come up with on my own.
