To update: the image retention is still present, even after running constant snow and/or white bar wipes for 12+ hours per day. It does not appear to have diminished.
I've been in contact with Panasonic technical support in regard to this matter and have sent them a detailed email in hopes of finding a resolution to the issue. A portion of this email, along with images, is included below for reference. Hopefully, if someone else has this same issue, it will help.
I'll update this thread with any information and/or fix information I receive from Panasonic.
Thanks again for all your responses and suggestions.

These two images show the image retention the most clearly. You can easily see the letters CND and AP, in addition to some lines. They appear almost pink on the white background.
Despite running the white bar sweep and black and white static for over two weeks, the image retention remains unaffected. I've been running the static and/or swipes for up to 12 hours per day.http://img841.imageshack.us/img841/7048/irimageonsm.jpg
As requested, this shows the image retention on top of an active image. Its less visible, due to the object obstruction, however AP can still clearly be discerned. I've noticed that the retention seems most visible on green, white, and blue imagery.http://img585.imageshack.us/img585/1...ionnoise01.jpghttp://img23.imageshack.us/img23/919...ionnoise02.jpg
Additionally, I noticed that solid white shapes, in general, appear distorted and slightly offset. This is most noticeable in the white sweep bar. Please refer to image 02 on the inside, right-side of the bar. You can see it looks like a wavy, squiggly linear distortion. In image 01 you can see how the white line doesn't 'register' properly on the left side and appears gray.http://img225.imageshack.us/img225/5...rnoise01sm.jpghttp://img64.imageshack.us/img64/480...rnoise02sm.jpghttp://img546.imageshack.us/img546/7...rnoise03sm.jpg
These images all show the excessive amount of noise in solid colors. A friend of mine who has the 42" model of this TV took note of this and said this was very excessive. His TV doesn't have this amount of noise or the other issues detailed above.
