Help with cooling on 260 GTX

[romeoagogo]

I finally got all my new parts for my watercooling setup yesterday and got to work, but have run into an area of uncertainty. I finally got my 260 GTX apart (yay!) and got my D-Tek block installed and placed some zalman ramsinks on all the ram (front and back). My question is, are there areas besides the RAM that should be sinked? If so can someone show a pic of what I should be putting the sink on? Lastly, if all I have are RAM sinks can these be used even if they look too big or do they need to be cut down to size or do I need order some other type of heatsink? How the hell would you cut one of these to size anyway? What tool would you use?

thanks

You can see in the pics where you should 'sink'

Ram sinks that are too big are not a problem as long as they fit, I think it's a good thing more surface area
