For an ecommerce site, the goal is usually sales, sales, and nothing but sales.
You can have all the quality content on the planet, but if it doesn't lead to sales, you have a problem. Is it directly causing a Panda issue? I don't know, but I suspect not. But if it's bringing you traffic that doesn't engage or convert, and if you don't have a clear idea on how to make it convert, then you have to ask yourself how much time and resources do you want to devote this content, on the off chance that one day - *maybe* - they suddenly start buying from your site.
Maybe there's a way you can be classified as a quality information site, but a low quality transactional site, I dunno. But it seems to me this content, as popular and good as it may be, is pulling focus away from your ecommerce. And me, I'd separate 'em.
There's a reason why, in landing page science, they tell you minimize the navigation and distractions on the page, and draw focus to the big orange BUY NOW button.
