Sorry if this sounds like fob off, it really isn't supposed to be. But it might be worth you phoning or e-mailing say geterbrewed and they can talk you through everything and give you a break down of the minimum gear required.
My Mrs. Got me a coopers starter kit with a young's American pale ale for Christmas last year. She organised it all over the phone with the local homebrew shop nd they put it together for her. Best present ever! All she had to do was nip in and they carried it out and put it in the car for her.
I've never asked but I reckon about 100 quid all in.
