"I was penalized by google because i use display:none or duplicated content?"

If you are trying to make a site that is guaranteed to fail in google, you're doing all the right things. Duplicated content pages will basically be ignored, since the pages you copied the stuff from will already be considered the source page, so those will probably never rank. Even if you get away with hidden text for now, with the amount you're putting on the pages you won't get away with it for long. And the chances are good that some time in the future your site will also drop out of yahoo and msn.

If you're going to use hidden text, use a more sophisticated method than display none, that's the easiest one to spot, though I don't think google looks to much at css libary files currently, though that could change at any time.
