I'm not exactly sure why you would want the alt= info in the file...
Does your HTML editor automatically extract it?

To the naked eye there's not much difference, at least to my eyes. In
theory floating point should be best, as you get the least precision
loss in the internal calculations. If you want to save jpg's in as good
a quality as possible set the q factor to 1, DCT to floating point and
subsampling to 1x1. I think subsampling has a bigger influence on image
quality than the DCT method.
