There are no gender distinctions in the pronouns regardless of dependent or independent status.
I have argued (in Kouwenberg 2007) that dependent and independent pronoun series need to be distinguished. Although the independent 3SG high-toned pronoun é can be used separately, to answer a question such as 'who is it?', it is more natural to use the emphatic form ele or to use a focus expression.
Sentence-internally, ele is mainly used as emphatic object pronoun. In subject position, the independent pronoun é can be distinguished from its dependent toneless counterpart by its fixed tone (rather than the variable tone of dependent e) and by the fact that it precedes mood marker lo (rather than follows it, as dependent pronouns do).
