lol, I'm an expert =) those guys probably have been studying this stuff for years!
If you can fit everything in 1040ez, then you can probably file it. I will file 1040, because I have a taxable refund (form 1099g that I got because last year as a non-resident I put my state taxes as itemized deductions). This is line 10 on 1040 and there is no such item on 1040ez.
I definitely cannot answer about the grant. However, your husband should have tax preparation sessions in his school (at least I had). I guess you can come together and they will help you both.
