Clubhouse and Upper Class Virgin.

Hi everyone. I'm new member to V-Flyer but certainly not new to Virgin
I've travelled with Virgin many a time but this time, for the first time ever, I'm splurging and treating myself and my partner to Upper Class.
We are flying to St Lucia from Gatwick next November and was wondering if there was any advice for a Clubhouse and Upper Class newbie? Is there restrictions to entry to the clubhouse I.e opening times, what clothes can you wear? How to make the most of the clubhouse?
When onboard with a returning night flight I've heard about night sleeping suits,can you keep these? Where's the best seat with the NEW A330 configure. Already looked online and it won't be the herringbone design.
Hope you guys can answer some of my questions or advise me accordingly. Many Thanks
