Yes they would rearrange themselves since E would be not be 0 and so there would be a force F=qE.
Now, since E=0 in the conductor then when solving for q in Gauss's law q is equal to zero. So, there should be an equal magnitude charge on the inner surface with an opposite sign (compared to the...

Oh. I believe it's in here: http://230nsc1.phy-astr.gsu.edu/hbase/electric/elesht.html
So the eq looks like E=charge density/2*epsilon. So this is independent of distance. I see.
