You can add buff display to party frames just like it's done with other frames, for example focus frame. Search for " --[[ Auras! ]]" comment in code and check the code starting with "if(unit=="focus") then" words. Same thing can be done with party frames, but you should write "if(not unit) then" and change some settings for auras. For more info about settings - check aura.lua file in \Interface\AddOns\oUF\elements folder.
To move party frames - simple change the point where to spawn it. All 4 partymember frames belong to one "header" frame, and its position is set in "--[[ Positions ]]" section of code. You should edit arguments for function "SetPoint":
Code:
party:SetPoint("BOTTOMRIGHT", UIParent, "BOTTOMRIGHT", -27, 27)
