Appreciate what you are doing but you've really only just begun to clean up. If I look at your latest links I can still see suspect links (obvious examples are the indian tour group and FIAT websites - they are clearly spamming). On top of the obvious ones is less obvious stuff like the generic titles/anchors that are being allowed, as well as the promotional/biased descriptions. Allowing "Best Audio Converter" as a title, isn't good. A better title would remove the promotional "best", and include the brand/sitename, e.g. JoyceSoft Audio Converters You would need to go through and audit all the listings for this to be a true pay for review directory. Directories who require payment, need to be far more comprehensive with editing than free directories because you are being compensated for the time spent editing/reviewing/maintaining the directory. Simply clicking "approve" when someone pays you isn't reviewing/editing. It's called an FFA site, and these are what Penguin will pop (to use your vernacular). If you wanted to be really taken seriously? I would also look at renaming your categories so they aren't the same as everyone elses. I would also look at redesigning, so your directory doesn't look like every other one on that default template. The more different your directory is (in content, design, categorisation, etc), the far less likely it is going to be popped by penguin, because penguin is looking for patterns, and right now you are in that pattern.
I thought FFA means free for all. If someone pays it is not for free, right? Anyway changing theme and categories is good idea to survive with google animals.
