Actually, that display:block is not being placed there by using Fluid Grids as far as I know. In fact, the problem is the way you are assigning that bullet image -
list-style-image: url(/dev/vip/assets/paw_bullet.gif);
Instead of that, use this -
background-image:url(/dev/vip/assets/paw_bullet.gif);
background-repeat:no-repeat;
padding-left:24px;
and leave the rest alone, although I agree with Osgood that the display block is also unnecessary. The list-style-image has always been unpredictable for me.
