Insert Multiple Rows and Values in Excel in various Places with VBA

I have a list of items in a sheet. I want to put two rows between them and add the same two tasks (Test, Install) to each item. The code below adds all the lines to the top of the sheet and not to individual rows. (The first half clears out rows I don't need). (Ross is just a place holder). I found this code and am trying to make it do what I want. I am not very good at this.

I've watched too many videos and search through code all day and cant figure this out. Any help would be appreciated.

Sub DeleteRowsBasedonCellValue()'Declare Variables    Dim LastRow As Long, FirstRow As Long    Dim Row As Long    With ActiveSheet'Define First and Last Rows       FirstRow = 1       LastRow = .UsedRange.Rows(.UsedRange.Rows.Count).Row       LastRow = ActiveSheet.UsedRange.Rows.Count'MsgBox LastRow'Loop Through Rows (Bottom to Top)       For Row = LastRow To FirstRow Step -1           If .Range("C" & Row).Value = "0" Then              .Range("C" & Row).EntireRow.Delete           End If       Next Row    End With    With ActiveSheet        FirstRow = 1        LastRow = .UsedRange.Rows(.UsedRange.Rows.Count).Row        For Row = LastRow To FirstRow Step -1            If .Range("C" & Row).Value <> "" Then                Rows("3:7").Insert Shift:=xlDown'Range("D" & FirstRow).Value = "Ross"                FirstRow = FirstRow + 1            End If        Next Row    End WithEnd Sub

Ive tried videos and searching other code. I've modified a bunch of different things I've found but none do what i need it to do.
