I wouldn't do anything hasty - let things calm down, get through the transfer period, and take the time to really get to know the site that you bought and it's users. Don't change anything until you know the site well, certainly not the branding or design. How long that will take depends on a number of factors, but it is measured certainly in months rather than weeks or days! You'll need to hand-hold your newly-bought userbase through any changes without alienating them with a radical change of direction, even if this means slowing the pace of change to less that you might want.

Only after reflection will you know how the two sites will fit together, and for that there are many possibilities, including piggy-backing the new site on the old or vice-versa, or moving both into a new space, each in a subdirectory.
