widget-title width / blog post positioning / breadcrumps

Sooooo…

I don’t want to make too many topics, so I will make one for three 😉

1. I want the widget-title to be as wide as the widget.. but, if I set it to 100% in the main.css file, its actually wider than the content of the widget.. how can I adjust that so that both are the same (I would like to shorten the title instead of widen the content) – first screenshot to show what I mean..

2. If you look at the second screenshot, you can see that on the main homepage, the width of blog entrys is within the main-wrapper, including the likes, date etc.. but if you open a posting, it becomes wider and date / likes overlap the main-wrapper.. I would like to have the single-post view like the main homepage view.. any easy way to fix this? (red circles 😉 )

3. how can i remove the breadcrumps row? (green circle)

oh, and how can i remove all those white horizontal lines? cant find anything in the main.css 🙁
