Reported 1098t on 2009 tax form. Looking back, I noticed the 1098t had box 7 marked that they included amounts for academic period beginning January - march 2010. Does that mean I do not report anything on the 2010 tax form even though I received another 1098t form for this 2010 year?

No, it means that the college factored in tuition that MAT have actually been paid in 2009 for the 2010 school year.
