If by cross-references you mean \ref and \label, those are implemented independently of reftex as new org-mode links, e.g. label:some-key and ref:some-key. There are a variety of completion options to make inserting these pretty easy. you can use reftex to insert citations in org-ref, but the default is now to use helm-bibtex which I find easer to search in, in addition to providing a lot more functionality for interacting with bibliography entries.
