Hi,
In answering your questions, I answered them for the monitor size of display. Please dont forget that this theme is responsive, and have multiple media queries inside (shrink your browser window and you will see the theme changing to fit into the window) .. so the font sizes, button sizes all change depending on the browser size. Please refrain from using pixels as much as possible and instead use either % or for fonts use em (instead of 15px use 1.34em)
1) Slideshow caption title css is below.
#top .caption_supersize .slideshow_caption h1 {
font-size: 60px;
text-transform: uppercase;
line-height: 1em;
}
the code for the slideshow caption text
#top .caption_supersize .slideshow_caption .featured_caption {
font-size: 15px;
line-height: 1.3em;
}
2)
The font css propety is below. just change it to whatever font you want and place it in the css above.
font-family: helvetica neue;
3) Good question. I just ran a test, and the answer is Both. The Quick CSS does *not* get deleted but it does *not* carry over from parent to child. So you can go back into parent and find one set of Quick/css and another set you can create for child. The benefit here is that you can have multiple child themes each with their own quick css so that you can compare what you like better
A child theme does not have custom.css file. You should add all custom css in the child theme style.css file so that it has a purpose other then the @import statement. You can of course create a custom.css file but that will just add an additional file to the load time and has no benefit whatsoever.
4)
#top .caption_supersize .caption-slideshow-button {
max-width: 150px;
}
#top .caption-slideshow-button {
width: 42%;
}
5) I can't answer that since I don't see it. If you show a url I can answer. There is none on the demo

6) This CSS will remove breadcrumbs
.title_container .breadcrumb {
display: none;
}
Thanks,
