I don't think so. Not in your case where the exemption + your loan balance leaves you equity in the home that is not exempt. The equity would belong to your creditors through the bankruptcy court. I think Des can confirm that.
If you are going to file bankruptcy anyway and discharge your debts, why throw good money away by paying anything. Again, strategy, not legal advice. Quit paying and start to squirrel away money you'll need for the bankruptcy.
One other thing, depending on how old your tax debts are, you might be able to discharge some of the older ones.
You've got some complicated issues. Consult a bankruptcy attorney and review your options.
