Welcome to the Q&A Forum

Patrick, SEOmoz only crawls once a month as they need time to process the data from the crawl. It is likely you will show up corrected within the next few weeks. If you did it just after a crawl and had to wait a month it would then be a couple of weeks before results show. So, likely within 6-7 weeks from when you removed redirect.  Hope this helps

It depends a bit on the depth and breadth of the products/categories you've got, but assuming the site has only a few dozen categories and maybe half a dozen brands/types, I'd go with option 2 and use subdirectories. They can help you in your analytics to sort and see what's happening in specific areas, can show up in Google with the category > subcategory delineation in place of the URL (which can help enhance CTR), and provide more detail (and a tiny bit more keyword relevance) for anyone looking at the URL in a browser, in email, in social media, etc. However, I'd stop before going overboard, e.g. site.com/laptops/thin-light/samsung/series-9 is fine, while site.com/laptops/thin-light/black/gray-highlights/samsung/series-9/make140/model2334 is not Use good judgement and you'll be fine! This post is still a reasonably good reference: http://www.seomoz.org/blog/11-best-practices-for-urls (though I should probably do a rewrite sometime soon)
