Note that, since you are OUTSIDE of the U.S. you have until 15 June 2011 to file (automatic 2-month extension).
The Form 1040-C is NOT required.
You each CAN file a dual-status return, in which case you report ONLY the U.S.-sourced income. You have no need for Form 1116 or 2555 on a dual-status return, because you will NOT claim the Italian income on your return OR the Romanian income on your fiancee's return.
If you both filed a resident return (Form 1040) for your 2009 return, you have the option of filing that way for 2010. In that case, you DO report the foreign income and you DO submit Form 1116 to request the Foreign Tax Credit.
Neither of you meet the criteria for Foreign Income Exclusion at this point in time. You MAY qualify if you remain in Italy or Romania and delay your filing until sometime in August.
Final note: If you opt to file dual-status, do NOT complete it yourself.
The dual-status is NOT for amateurs; get professional help!
