Dimension Extension Lines and Leader Help

Hey,

Just need help with three issues that I can't seem to modify in the settings.

1.  I can't seem to figure out how to get the lines, while inside the extension lines to not have the line extend across the dimensions (http://i.imgur.com/Qg97miz.jpg as an example)

2. I'd like to remove the extension lines from dimensions so that they just point to the dimensions and not underline the value (example -  http://i.imgur.com/7AFt42Z.jpg

3.  Not related, but is there a way to have an Overall Drafting Standard stay as what I need and not have to reset it every time?

Thanks in advance.
