Given that you were lawfully admitted into the country upon your last arrival,
you will be ale to file for adjustment of status in the US and will not need to depart and file the waiver to be readmitted. That waiver requirement is not applicable to you since you were lawfully admitted into country and are thus free to apply for a green card and obtain it in the US.

I assume that you married a US citizen after you came in the US the last time. In that case you do not need to file I-601. I-601 is an Application for Waiver of Grounds of Inadmissibility. You were admitted in the US, therefore, you were admissible at the time you received your visa.Ask a similar question
When you were in the US 7 years ago and overstayed for two years, then departed, you incurred a 10-year bar to adjustment of status.
However, if when you were here 7 years ago, you were on an F-1 visa with "D/S" indicated on your I-94, then you might not have accrued the unlawful presence and would not need the waiver now to be able to adjust status.
Obviously, be sure to discuss this in detail with a good immigration attorney. Most of us are available via phone and Skype.
