Of course your lawyer has "a chance" but one would have to know more facts to analyze or evaluate. If you try to defend against a lawyer without a lawyer, it will not be easy. This matter with your "old" lawyer would probably get settled if your "new" lawyer intervenes.
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

It depends upon what she claims on her complaint. However, she would have to get a judgment against you before she can attempt to garnish your wage. You should consult with attorneys in your area.
This is general information, not legal advice. This does not establish any attorney client relationship.
"There is a section in my state's RCW that says (I'm paraphrasing): "A lawyer has a duty to provide reply to his or her client in a timely fashion"." There is no such section in the Revised Codes of Washington.
On another hand, the Rules of Professional Conduct for attorneys do require that attorney "(3) keep the client reasonably informed about the status of the matter". RPC 1.4. The RPCs are at http://www.courts.wa.gov/court_rules/?fa=court_rules.list&group=ga&set=RPC .
The reason why I wrote the above is that you need to hire an attorney. If you do not know the laws and the rules, you likely will lose the case even if your case has merits.
If the WA State Bar Association investigated your complaint and did not fault the attorney, you may in fact end up owing the attorney her fees. The WSBA is the entity in WA that licenses and regulates attorneys in WA on behalf of the WA Supreme Court.
