I'd actually cut the C60 to 1/2lb - Special B is a crystal malt too, and your extracts have crystal in them as well.
Ditto what Oldsock said re the hops - don't try and compete with the coffee. I'd probably do 1.5 oz of East Kent Goldings for 60 minutes and leave it at that.
Stop using so much caramel malt. Your beer will thank you.
(yes, Carapils is a caramel malt...so is Special B)
