A fix for the section header issue that I've found useful at w:c:tardis is simply: Your milage may vary on the definition you give to, but that at least allows you to control the margin.

And TOCs, like lists, are handled by, as suggested upthread. We set the  value to 1.2em. But I guess that's basically about 20px in our standard, serif fornt. 20 px would seem a bit huge to me with Arial, but all that's a matter of taste. Point is, is how you control bulleted lists, numbered lists and TOCs.
