Your first screenshot looks very weird, indeed. Wonder how you got that.
With what you have now, and getting to what you want to have (which is well possible, of course), I don't think you'll get there without you knowing and understanding first what causes the present weird appearance as well as then some PHP and/or CSS. Or, for anyone here to be able to help and guide you, a link to your site on-line.
Furthermore, and the above provided, I'd recommend to make this new issue a new topic in the forum where it belongs: "Product & Category Display" - instead of here under "Archives", which is obviously just a repository for rock-old threads.
Sorry, but as a side note, both I and my dictionaries don't know what you mean by "impostation".
