Several Questions about customization

Hi there! First I want to say that I LOVE the Minimatica theme, so simple, but classy. Great job Daniel! I am a newbie to WP and it’s turning out to be perfect for the website I am creating. I have been able to customize it a bit on my own. These forums have been so helpful, you guys rock!! I am wondering if anyone can help with with a few more things I would like to tweak. I searched through here and on WordPress and haven’t found any solutions for these questions. I can’t wait to share my website on here when it is finished! Here are my questions (sorry, I have a bunch!)

1. I moved the menu to the top already, but now I want to center it. Does anyone know how I can do this?

2. I would like to add a feature to “highlight” in yellow when you hover over each of the menu titles. Is this possible?

3. I’ve been trying to make my logo in the header a “clickable link” that goes back to the main page, but I am still having issues with this. I read a few different posts on what coding to add to the header which I have tried a few different times. When I add it to the header, coding text shows up on the page. I think it probably has something to do with the fact I moved the “footer” coding for the menu to the top so it’s not working properly. Any idea how to fix this?

4. Which leads me to my next question, since I moved the footer menu to the top, I can’t seem to add any widgets or coding to my footer now. When I add anything it goes to the top of the page. How do I fix this?

5. Is there a way to move the right side bar further to the right side of the page and/or make it wider?

6. Is there a way to add my “FB and Twitter” button links on the top right hand side next to the logo in the header?

Thank you so much in advance if anyone can help with any of these items!
