Answer 1

This is the code that sets a border around each cell:

xlWS.get_Range("C9", "N9").Cells.Borders.Weight = XL.XlBorderWeight.xlMedium;

Answer 2

This code puts a border around the area from (row1,col1) to (row2,col2). Individual cells do not get a border. The variable color is an integer color index number. See http://www.databison.com/excel-color-palette-and-color-index-change-using-vba/ for a list of index numbers and their corresponding colors.

    Range cell1 = worksheet.Cells[row1,col1];
    Range cell2 = worksheet.Cells[row2,col2];
    Range range = worksheet.get_Range(cell1,cell2);
    range.BorderAround(
        Type.Missing, XlBorderWeight.xlThick, (XlColorIndex)color, Type.Missing );
