"I saw in one of zacuto's shootouts someone saying that an 8-bit video has X tones of a color (eg: brown), and a 10-bit has more browns and so on" - 2^8 = 256, but then in broadcast video black is not 0, it is 16. Also white is not 255, it is 235. So you have less gradations, and these are not that many. 10 bits gives 2^10 = 1024. Simple math which you can calculate, you don't need Zacuto to tell you that.
"If I convert an 8-bit video to a format with more latitude, can I recover those "lost" (or hidden) informations?" - No. You cannot get information if it is not there. But a good interpolator can smooth up rough edges and reduce banding.
"another question: considering the same camera. If I record in that camera a video with 28Mbps and do the same shot with 200+Mbps, will I be able to recover more info and increase the dynamic range, even if its hidden and cranked in a bad codec (because I may be able to recover that info)?" - Higher bitrate mainly affects tiling a.k.a. macroblocking and therefore, how much detail you see. I guess more detail may affect contrast.
