O editor do Eclipse não é muito bom para JSF. Você precisa declarar os namespaces da tag na mão. Ou seja, na tag html, você tem que declarar o xmlns:h assim como o xmlns:f. Porém, você ainda vai se deparar com alguns bugs referentes a regras de navegação implícita e o com a UEL, que não tem autocomplete. Pelo menos em termo de JSF, o Netbeans é beeeeeem melhor.
