WP Table Reloaded issues

I have a "problem" with WP Table Reloaded. I wanna change the language for the search button and the bottom text, the part that says "Showing 1 to 24 of 24 entries".

Furthermore: The text in the table itself is normal in Chrome, but in Firefox and IE the text suddenly becomes bold. I need the text to be normal like it is in Chrome.

Edit: Oh, one more thing. In IE and Firefox, when you scroll down, there's this menu to the left. It's not supposed to be there. I edited the width of the sidebar and.. whatchacalling it.. the post part (?), so I guess this is what did it. But I just wanna remove the whole thing. The thing to the left that is. How do I do that?

Any suggestions?

For bold text, go through css style files, and search for duplicate file-weight values for same objects
