You should seek a more extended consultation with an immigration attorney but from what you have written it sounds like you could reapply/seek consular processing. On the taxes, your husband is only required to submit his last year's taxes. Note that he would still need to file an affidavit of support as petitioner even if your in-laws agree to be a joint sponsor.
Best of luck,

Making several assumptions, the answer to your questions is probably Yes, as long as you can prove that your marriage is bona fide, you are not subject to a 3 or 10 year bar to reentry and you have the support of a US resident or citizen with income sufficient to support a affidavit of support. As for your husband's tax issues, additional details and research are needed to give you a reliable answer.
