What are the rights of a divorced woman after she has been given a first, absentia, revocable divorce, and what is the ruling on the husband taking the gold and gifts that he or others gave her?

If the husband pronounces a divorce, it takes effect, and the absence of any guardians (awliya') or mahrams does not affect its validity. You are entitled to the full dowry (the prompt and the deferred) as long as your husband has consummated the marriage with you, and you are entitled to your maintenance for the duration of the 'iddah (definition) (waiting period). The gifts that were given to you are your property, and your husband has no right to them.
