oUF doesn't handle tooltips, but it's simple to add them:
Code:
frame:SetScript("OnEnter", UnitFrame_OnEnter)
frame:SetScript("OnLeave", UnitFrame_OnLeave)
For menus, I can't recall offhand, but I think unit buttons might not be registered for right-clicks by default... try adding this:
Code:
frame:RegisterForClicks("AnyUp")
