You want an O.G. of around 1.052 - 1.054 (this recipe gave me 1.053). Bittering hops in Fuller's, from what I've read, are not Bullion but Challenger, Target, and/or Northdown (which can be tough to find). Any high AAU, British hop should get you pretty close as long as you finish with Goldings.
The flaked maize is a must and needs to be 8-10% of your total grain bill. I used the dark Belgian candi sugar to try and get a little closer to the right amber/orange color (my first try came out too light).
If you don't want to mash any grains, I'd suggest using another can of M&F, and a pound of corn sugar instead of the grains. You could darken the beer a little by carmelizing some of the extract (leave your kettle on the burner when you add the extract).
