Heathrow & 787

Hi
New member here ( well I say new, I registered years go but this is my first post). When flying with VA I've always flown from Manchester living in Sheffield or for other long haul utilised KLM and changed in Amsterdam. However Ive booked onto a LHR-PVG with Virgin and am just wondering how different the 787 are from the 747 and A330 used in Manchester . Im struggling to work out where passengers board from and wether or not you can board last in UC . This was never a problem at MAN however I didn't know if using the clubhouse would affect this in anyway. On the subject of the clubhouse what would everyone recommend to eat, see and do on a first visit there.
Thanks
