やりくり ('juggling, making ends meet, managing resources') is a conversational noun for the ingenuity required to manage limited money. 上手 ('skilled at') takes が on what one is skilled at — like 好き, another 'takes が' adjective. The relative-clause structure やりくりが上手な ('[is] skilled at juggling') modifies 奥さん ('wife, Mrs.').
