Basta vc clicar com o botão direito no pacote e selecionar Refactor>Rename.
Vc tb pode selecionar o pacote e apertar alt+shift+R, que no Eclipse serve pra vc renomear classes, variáveis, atributos, métodos, pacotes, diretórios, projetos, etc... Ou selecionar e apertar F2. O rename dele sempre atualiza as referências através do código. Inclusive quando vc está mudando métodos, variáveis, parâmetros, etc... No caso de classes é a melhor forma, pq ele renomeia o arquivo da classe também. Se esquecer do atalho (alt+shift+R), basta ir no botão direito (menu de contexto), selecionar Refactor>Rename (o atalho aparece do lado). Abraço Peter P.
