How/where can I modify the main table that creates the center column and sidebars? By default, there is a dashed border between them.

I'd like to have either cell spacing with no border (to let the background show through), or simple set the border to the same color as the background.

that is caused by the 'border-right: dashed 1px #CCCCCC;' in the option AOT->Style & configure SIDEBARS->LEFT sidebar style (and the othere) just set the 1px to 0px
