Swatch Legend Generator Script (Spots only) help

Hi I have this script for generating a legend of the swatches however:

1) I only want to show the SPOTS and not any cmyk / rgb / colours (as described in the image at the bottom)
2) I want the height of the text box to go three lines deep not just two (as indicated by the image at the bottom)

How would you modify the following script to achieve this? – I'd be very grateful for any tips...

SCRIPT:

doc = activeDocument, 

swatches = doc.swatches, 

cols = 4, // number of columns in group 

displayAs = "SPOTColor",  //or "CMYKColor" 

printColors = ["SPOT"], // RGB, CMYK, LAB and/or GrayScale 

textSize = 6, // output text size value in points 

rectRef=null, 

textRectRef=null, 

textRef=null, 

swatchColor=null, 

x=null, 

y=null, 

w=16; // width of ellipse

h=16, // height of ellipse

h_pad = 45, //distance between swatches horizontally

v_pad = 10, // distance between swatches vertically

t_h_pad = 55, //width of text box

t_v_pad = 2, //vertical position of text box - more means lower

activeDocument.layers[0].locked= false; 

var newGroup = doc.groupItems.add(); 

newGroup.name = "NewGroup"; 

newGroup.move( doc, ElementPlacement.PLACEATBEGINNING ); 

for(var c=2,len=swatches.length;c<len;c++) 

{ 

    var swatchGroup = doc.groupItems.add(); 

    swatchGroup.name = swatches.name; 

    x= (w+h_pad)*((c-2)% cols); 

    y=(h+v_pad)*(Math.round(((c)+.03)/cols))*-1 ; 

    rectRef = doc.pathItems.ellipse(y,x, w,h);  //circle or rectangle

    swatchColor = swatches.color; 

    rectRef.fillColor = swatchColor; 

    rectRef.stroked=false; 

    textRectRef =  doc.pathItems.rectangle(y- t_v_pad,x+ t_h_pad, w-(0.95*t_h_pad),h-(1*t_v_pad));  // padding between ellipse and text box

    textRef = doc.textFrames.areaText(textRectRef);

    textRef.contents = swatches.name; 

    textRef.textRange.size = textSize; 

    rectRef.move( swatchGroup, ElementPlacement.PLACEATBEGINNING ); 

    textRef.move( swatchGroup, ElementPlacement.PLACEATBEGINNING ); 

    swatchGroup.move( newGroup, ElementPlacement.PLACEATEND ); 

}
