1, The Directors recipe I have in the Wheeler book matched quite closely to the weight of pale malt and crystal malt I have at the moment. I just had to nip down to the homebrew shop and pick up some black malt and hallertau hops.
2, I do enjoy a good pint of Directors

23L
============
Pale Malt 4000g
Crystal 250g
Black Malt 25g
Invert Cane Sugar 454g (1 tin of golden syrup)
51g Challenger at beginning of boil
Recipe looks for Target but I am using up some challenger that I had in the freezer. I have simply adjusted the amount used to account for the lower alpha acid versus the target.
15g Hallertau last 15 minutes
The recipe actually prescribed 5g Hallertau and 10g Styrian but the latter was not available so I will simply use Hallertau.
Safale s 04.
The plan is to get the mash tun and boiler wiped down and the yeast starter on the go tonight (I'm using some spray malt for this). Tomorrow morning before work I will get the water ready in the boiler. I will call my wife as I am leaving work to turn it on for the mash water. As I am planning to leave early it should only take me about 40 minutes to drive from Edinburgh to Dunfermline so by the time I get home I expect to be able to dough in.
I have been keeping an eye on the "Batch Sparge v Fly Sparge" debate which I have found most interesting. I have always sparged by using a watering can rose to sprinkle and stopping when I thought the gravity was getting low. I think from the information gleaned from the discussion I will perform a single batch sparge after the original mash liquor has been drained and then return to the sprinkle method to get any remaining sugars out of the grain.
