Having issues with Sela Theme

Sela Theme – couple of issues I need help to resolve.

1. How do I change the social media icons (bottom of each page) from pink to #529FC2″ branded blue. I managed to change the navigation color bar, however am unable to figure out how to for the icons.

2. I would like to learn how to add a link to my company name on the bottom credits, how do I do this?

3. After I created the “front page widget areas to have 3 images with headlines – I see that it added to the home page and contact page. I would like to remove them off the contact page – how do I do that?

4. I created sections to match the original theme – About Us — Map to Stitches — Contact Us. Some pages orient correctly while others dont. It appears that on the home page and contact page is where the issue is, could be due to the addition of the front page widget.

5. I also get a error “sometime I get a error “https://developers.google.com/maps/usagelimits/
How do I fix this?

6. To my contact form, I added a telephone number. The field is actually darker than the others already created, however I made no adjustments. How can I fix?

7. Gallery page: I would love to add similar vertical white space to match the horizontial white space (between images placed on page), how do I do this?

Would appreciate your insight on how I can understand how to solve these challenges.
Thanks,
Christina

Ps. Im a beginner, so please excuse my current status. I do love this theme and wordpress.
