The W-2 being in her maiden name is not a problem - it's the social security number that's important.
She should complete her AL return (Form 40) as a part-year resident, reporting her income received while a resident there. Then you fill out your MS return as part-year residents (form 80-205), reporting all your income including her AL wages, and take the credit for taxes she paid to AL (you report this on line 25 of 80-205). You will have to attach all W2's and a copy of your AL return to your MS return to document this.
Your filing status for all forms is married filing jointly - if you check the instructions for Alabama Form 40 is specifies that your filing status is based on your marital status as of Dec 31.
