UC way out, PE back

We've just booked flights for November to BGI and are treating ourselves to our first ever UC trip, returning PE.
I think I have worked out from other posts on here that we really want to get 4A and 5A on the way out (as I know that is the side of the plane you get a view of the island from on approach) and to avoid any seats in the middle (A330). I hope that is correct?
On the way back we're on a 747 and we've only ever flown PE in the old 747 config where we chose upstairs. Having been on the new 747 config with economy upstairs with some of the PE, I am not sure what to choose. We used to try and get the seats at the back of the front block upstairs on the left (A/C), so we could put our seat back and not disturb anyone, but this would be backing onto economy now, so not sure about that. Are there any recline restrictions on any of the back row PE seats downstairs? Can't book our seats yet, anyway, but when we can I want to make sure we get the right ones! Thanks for any help.
Also, any tips we should know for using the clubhouse at LGW, as never been there before?
