U/X Best Practices? Any Leads?

Hi all, I just launched a private beta of my site, an online Q&A platform for style related advice, called GoodToGoOut (www.goodtogoout.com), and I'm trying to work on doing a redesign of the UI to provide to my developer for the product's next iteration. Does anyone have any resources for best practices or anything that might be helpful when weighing ideas and actually illustrating them? I already have programs for wireframing, etc, but just want to find more common wisdom and recommended ideas for social site design. Thanks!
