I just inastalled the NoiseNija plug-in from PictureCode.  I used it on the earlier high ISO photos I took with some great results.

Each group of 3 pictures for the basket are presented in this order:

1.  ISO (100% crop, no filter)

2.  After ISO specific noise filter has been applied

3.  ISO100 100% crop for comparison

4.  Full image @ ISO with no Ninja

5.  Full image @ ISO w/ Ninja

6.  Full image @ ISO100

ISO800

ISO1600

ISO3200

Here's my accidental ISO3200 suirrel shot (100% crop) before and after Noise Ninja:

Here's the full squirrel image before and after Noise Ninja:

A nice add on for those that want to shoot higher ISO's.  For the ISO3200 profile, I used the 10D ISO3200 profile.
