Answer 1

If your wife is a US citizen then you can apply for citizenship in 2011. If not you will need to wait until 2013.

Answer 2

5 Years from your green card approval date, in general.

3 years from your green card approva date, if you got your green card through marriage to US Citizen.

Since you got your green card in March 2008, you can apply citizenship in December 2012, if you are going 5 year general option, or December 2010, if you are going marriage.
