yes all of this was before I asked this question.  I did find where the sensor is...and moving the mirror back does not affect the sensor.  You have to use a menu function that will hold the shutter open and the sensor is behind that.  so I believe the sensor is in fine shape.  Just this view finder pentaprism is dirty.  it does work fine.  So I will take it to a professional to see if they can clean or replace the viewfinder items.  I just took at 30 second out of focus picture of a white piece of paper and zoomed in as I viewed it with paintshop pro...it looks clean as a whistle..no spots or anything that I can tell.  SO lets hope I have not messed anything else up.
 
I do appreciate the warnings and advise, which I will...from now on...adhere to!!!!!!!!!!!!!
