Mmost of them are 1.0 :(. Like, I'm really feeling the 8-Bit layout. Is there not anyway we can use them for 2.0 profiles?

Check out this topic, see if it helps at all.

Gaaaah this is really complicated. What's a hex code and how do I know which code(s) hide things on 1.0?

A hexadecimal code is a colour in hexadecimal values, and it defines what colour an element should be. For example, black is #000000 and white is #FFFFFF. Anything with display:none; pretty much hides objects on 1.0 pages. Another choice would be to ask the designer of the layout to convert the layout for for you. It's worth a try.

Try this: http://fixtatik.com/projects/2.0-converter
Not sure how well it'll work for that layout, but it doesn't hurt to try.

Oh wow, definitely linking that for future questions regarding 1.0 to 2.0 conversion.
