Also, I don't know if this means anything, but the shimmy is worse when it's hot outside, right now, after getting home from watching Godzilla with the family(It was awesome GO SEE IT IN THE THEATERS) I took my car out for a spin and it was about half as bad as it was when it was 100F outside.

If you drive 55mph while drafting trucks you are going to see a pretty nice gain in your mileage , about 10 more mpg I estimate.
Your temperature issue is probably (more than likely) the tire expanding to do the increased psi from the heat on the damaged tire/tires causing the weak spot to bulge.
I have personally seen curb damaged tires bulge then with a reduction in psi the bulge lessened , those tires was shot and was replaced in real short order.
In your case higher psi should be avoided , not sure what psi you are using now. Following this avenue you could raise the psi in each tire(individually) and road test to see which tire causes the shimmy to increase.
that test is free , if you have access to free air it will pin point a tire IF it is as I suspect and I Bet(the price of air) that you find a bad tire/tires.
