The way I always post pictures is I put them on the desktop of your computer then click the "additional options" when you reply. Click the "browse..." and find the picture file under the "desktop" menu.
There is some debate here on the forum regarding smoothing Stilton. Personally, I like them smoothed once. Others will say that there is greater character in un-smoothed. It's really just a personal preference, unless you want to dry-salt the exterior to keep it clean. Then, I'd say smoothing would make it easier.
Unless the blue mold was heavy on the outside, it should be fine. I think the only concern I would have about it is if the curd used to smooth wouldn't stick because of a thick layer of blue mold. In that case, it would probably flake off as it dried. Then you'd just be left with the un-smoothed rind again.
I'm not sure exactly how long the blue spores will keep in the cheese, but really they will live much, much longer in an un-pierced cheese than you will probably need them to. I pierced my stilton at 6 weeks with no ill effects. Generally, they're pierced after just a few weeks, or until there is a thick blue bloom on the exterior.
