Home Page Specifics

Hi! I hope you are well. I have been working on my website and am (finally!!!) thisclose to being able to tell customers about it. It is https://www.sleeneys.com. I’m using a child version of the free Virtue theme.

There are a few small changes that I’d like to make:

1- I would like to switch the social icons and magnifying glass at the top of the site. I would like for the social icons to be a tiny bit bigger and on the left side. I would like for the magnifying glass to be on the right side, next to or under the cart. I would also like to add the word “search” next to the magnifying glass.
This is the custom code that I have for my topbar:
#topbar-search input[type=text] {
color: black;
}
#topbar-search #searchsubmit {
color: black;
}
#topbar .kad-mobile-nav .form-search :-moz-placeholder {
color: black;
}
#topbar .kad-mobile-nav .form-search ::-webkit-input-placeholder {
color: black;
}
#topbar .kad-mobile-nav .form-search ::-moz-placeholder {
color: black;
}
#topbar .kad-mobile-nav .form-search :-ms-input-placeholder {
color: black;
}
.topbar-widget {
color: #000000;
}
.topbarmenu ul li a {
color: #FFFFFF;
}

2- I need to center the text under the category photos (“Accessories”, “Clothes”, “Vintage Jewelry”, etc). I would also like to change this font (the style and size) and have it link to the appropriate page. The photos link to the products, but I would like for the text to link, also, if possible.

3- I would like to add a little space below the second row of category photos (Vintage Jewelry, Vintage-Inspired Jewelry, and Sale Items) and above the footer menu. Where do I go to add just a little bit of blank space?

4- I would like to blacken the search widget at the bottom of the website (if possible, but not a huge deal) and move my footer credits to the center of the page. Is there a way to specify the layout (move the SSL cert., the search, and social icons to the left a tiny bit)?

THANK YOU SO much!!!!
