Problems with GRUNGE WALL theme

Hello I have searched the forums and these issues have not yet been resolved with the GRUNGE WALL theme. If anybody has any information about these issues I as well as many others would be grateful.

1. Certain widget texts are either the SAME or ALMOST the same color as the widget background in question. My page is: https://www.DASHOWCASE.com – as you can see, the number of posts in my “select a BIZARRE channel” widget cannot be seen because it is the SAME color. Also my “daily SHOWCASE wisdom” widget has text that is ALMOST the same color making it very difficult to read.

2. Posts in my categories do not display fully. There is a “read more” link that cuts them down to just a few pictures until one views the post individually. Here is what I’m talking about: https://dashowcase.com/?cat=24

3. Where would I go to change the bottom of the page (C) abbreviation and “powered by wordpress” phrase?

SOMEBODY PLEASE HELP =/
