I am a CPA. Last year (2008 actually) a short term client went out of business after a very short while. The employee kept calling me about the W-2, which I really had no control over. However, after discussing the situation with both IRS and Social Security, I went ahead and filed the missing W-2 and W-3 for the employer anyway. The main thing was I knew my figures were accurate and I knew the employer was not going to do anything.
If I had not done this the employee could have filed Substitute W-2 Form 4852. However, this form cannot be used until at least March since employers actually have until February 28th to get W-2s filed without penalty. DO NOT use your pay stub as a W-2. The IRS is now offering to penalize at least preparers who do this. The same applies to some 1099s, but not to the 1099-Misc. You CAN file without receiving your 1099-misc, unless it includes withheld income tax.
Since it appears the former accountant or payroll service is going to take care of it, your problem sounds solved.
I hope I was helpful. Feel free to ask other questions, especially if you are wondering about the Adoption Credit, a specialty of mine.
