I think the answer to the dust spots is to clean the sensor. I struggled with dust-busting until I discovered a technique to get the sensor of my 1ds clean. I have heard that the 14n is easier to clean so you should be able to shoot without dust.
There should be something in the archive about this but if you cannot find it I'll try and find it and re-post.
I quite agree with you that one needs to keep the sensor clean but there is always that bit of dirt that appears in the sky at the start of the day and trundles around all day until one discovers it that night after a 100 shots. The 14n is actually the pig of a camera to clean as with the full frame chip, cleaning tends to get all the dirt into one corner and there is no "gutter into which it can be swept.
And to be honest is does not matter how much one cleans the sensor, it always seems to gather bits of dust. As i noted before I am convinced that the mirror creates vortices which move the dirt about. Changing lenses is another problem as it allows atmospheric particles in and there is always swarf from the lens bayonet mount, especially with Nikkor lenses. I have followed your advice of using double sided tape inside body and lens caps and now store my lenses body cap down. I can also suggest using zoom lenses very slowly as Fixation will tell you that the zooming elements inside the lens act as bellows, blowing and sucking fine dust about inside the lens barrel.
Indeed for me, dirt on the imager is the one constant and consistent problem with digital shooting. As I tend to shoot in a lot of different and frequently dusty locations it can be a nightmare. The old Kodak 760 had a filter across the throat of the shutter box so if one got the sensor clean then it stayed clean and indeed i did a month shooting in Greece without any dirt at all. But the 14n - you can clean it and then find that the first frame thereafter has what i try and explain to my clients is simply a big black crow!
