A couple of other points:
The two pads in the component concerned are of course surface mount pads
(with a hole diameter of zero). To prevent them from being imaged on the
Gerber file for the Paste Mask layer (on the same side of the PCB), set the
Paste Mask expansion value to a sufficiently negative value so as to mask
these pads on this layer. (This can be done with a Design Rule, or from the
'Pad' dialog box invoked after clicking on each of the pads concerned.)
And unless you want the copper in the area of these pads to be exposed on
the actual PCB, similarly mask these pads on the Solder Mask layer as well.
(Again, either by defining a Design Rule, or from the 'Pad' dialog box.)

Geoff Harland.
