box order

I know this has probably been asked a zillion times, so forgive me. I did try searching but there are so many related posts and I was too lazy to weed through them for an answer!:no: I have a supplier that is offering Russian bees which I've heard good things about but I've not hived before...

I have some extra comb and honey on bars from last year. Should I put most of it in the top box and leave bottom box with less, encouraging them to build down? If so I did it wrong today and once the queen is released I'll reverse the two boxes.
