Is it pretty easy to have an auto glass place remove my windshield and redo the seal?

its very easy. I just did my front and rear seals on my valiant. my neighbor owns an autoglass company and helped me along the way to make sure I did it correctly. don't buy any seals other than from steele products they make the best and the fit was perfect. all you need is a special tool to remove the trim and 1 to remove the glass from the seal. after it is all installed we put in a special caulking made for the old style seals to make sure they don't leak anywhere. it took me a few days to complete but it was my first time doing it.
