Hi,
1) All CSS should be defined in either custom.css or added directly into Quick CSS which is a text area located in the backend Choices > Theme Options > Styling ... at the bottom of the page, and hit save.
To style every single h1-h5 red in the entire theme you would add the css to quick css and save
h1, h2, h3, h4, h5 {
color: red;
}
The Quick CSS is an empty text area where you dump your css to override the current CSS. To get the CSS you need to override please watch video below.
https://docs.google.com/open?id=0B8hqGBMSfHtKNE51dUJPZGJwdlE .. Please watch a video I made to show how to use Google browser to easily change CSS without knowing anything, then save it, I go through the workflow of changing a menu colors without knowing 1 css command. (I am acting, but very convincingly I am told).
2) The only way to change existing images is to first (a) change some setting within the theme (b) regenerate all the images. If you change the settings but do not regenerate , then only new images you add will have new settings while the old images will remain with the old settings. a good plugin to do just that is http://wordpress.org/extend/plugins/simple-image-sizes/ , after activating it, in Settings > Media you will see a whole lot of options added for various image sizes used in your theme. and on the bottom there is a regenerate button (which will also be added to various admin menus.
3) Portfolios are added in Choices > Template Builder. (a) Create a new template and give it a name. Add a portfolio block to it. Customize it (one f the options is whether you want those overlays or not), save. (b) create a new page and on bottom right add the template you just created to the page thereby turning that page into a portfolio list .(You can also add a blog there too if you wanted, or 5 portfolios and 8 blogs) You need to watch some videos I've made showing the fun you can have

4) to remove the magnifying glass , please add this to quick css described earlier
.pp_expand {
display: none !important;
}
Thanks,
Nick
