Answer 1

Productivity Power Tools for 2010 in the Visual Studio Gallery can do this, it took me a bit to find out how I did it, but in the Tools->Options... menu, there is a "Productivity Power Tools' drop down.

The default for the 'Words matching the caret location color in the editor' is fully transparent, so it isn't used. A color choice dialog pops up and you can set the color. Just ensure you set an alpha value above 1 to enable it.

The color values I used below are [153, 138, 188, 219] It seems to work well in light themes.
