I agree, not good for you to visit the Philippines until the case is solved. If you have been blacklisted, you will be denied entry into the country or worse ... they'll grab you and put you in prison right away. Remember the Immigration motto... "Good guys in, bad guys out."
Clearing your name is, of course, very important. If you're going to hire a lawyer, make sure you have unlimited funds to pay for the lawyer especially since you're going to be dealing with the lawyer long distance. This case could drag on for years and years.
Good luck!
