Just go for 1kg of Light Dry Spray Malt, forget the sugar.
You could also make a 'Hop Tea' with maybe some Fuggles of Goldings hops... Just steep a few grams in a litre of boiling water for 15-20mins, strain through a sanitised sieve and add it to your fermenter with the kit when you are mixing it up.

You might like to try the 'beer kits' part of the forum too
