Only three other things I can think worth mentioning;
Jersey zone often ask you to report 50N, so know where it is,
Alderney is notorious for sea fog setting in really quickly, so be prepared,
the airway is a pain if you are staying outside and inevitably keeps you low, I forget the issues routing to the west (which I know would suite you) but I do know the alternative is to route just to the East (St Catherine's Point) to just East of Ortac - that way you stay outside the airway and to the west of the danger areas so you are basically free to go as high as you like without having to ask anyone. If outside the airway that is the way I always go.
