One of my posts has a picture of the area that needs to be taped. It's easy. take wide masking tape and cover the vertical section of the mirror that I point to in my pic. If your wind noise goes away drastically you have the bad mirrors.

As for the weather stripping, you can adjust the door striker inward a bit to make a tighter seal. I would try this and see if it helps. If not, your weather stripping may need to be replaced. The ones on my 07 that I had were replaced and it helped a little bit. The 07's in general are a bit more prone to wind noise, I can't say exactly why, as I can't see any real differenc, but my 08 is quieter. You will still hear some wind noise. You can move a 6,000lb object at 70mph and not have some wind noise.
