The basis is good but I would drop at least one of the bittering hop additions and move them to the whirlpool.
What temp and time are the whirlpool? as this will have a effect on your IBU's, if you like high IBU's don't worry but if you are bitter/IBU sensitive like me then you need to plan your whirlpool temp and time to suit.
Make sure you only use the zest of the grapefruit and no white pith as that will impart a bitter taste

Cascade give a good grapefruit taste so as The Baron said move the Cascade bittering hops to either whirlpool or dry hop so you double the quantity

I think you're right, my IBUs were coming in at the high 40s which I was a bit concerned about. I think I'll move the cascade to whirlpool (going to WP @ 80c for 20 mins) and see how that goes. Cheers guys!
