Monodevelop visual style questions

Hey everybody! I had a few really simple questions about setting up monodevelops visual style. Currently I run monodevelop with the IRBlack colorscheme and really love most of it! There are just 2 things that I would REALLY like to have in my visual layout currently.

1) Is those neat little lines some IDE's put in there to help you "track" your braces. I went ahead and took an image out of notepad++ so everyone could see what I'm talking about.

2) Secondly while I do love my dark colorscheme my "current line highlight" is colored in a way that it is almost indiscernible from the rest of my file. Is there an easy way (any way?) to change the current line highlight color?
