Craftster.org is a great resource. They have 2 sections dedicated to sewing and asking questions and reconstruction. There are a few others out there too.
I love reviews, especially on Amazon, as it's one of the few sites that everyone goes too. Reviews are how I decide on buying major things.
Quality of clothing is a gray area, wal-mart is cheap and so are thier clothing, I buy kids clothing there, but then they grow out of it faster than it can be destroyed sometimes. Price doesn't mean much, I've seen expensive clothes made cheaply and more inexpensive clothing made better. Feel the item, for example, a cotton t-shirt, a 'better' jersey will have a thicker feel to it, so will last longer. I sew a lot, my stuff, even put together half a$$ed last longer than the stuff we buy at the store, but on that note, material isn't cheap, so making clothing isn't any cheaper at times than buying, it's determined what your looking at. For example, I love the look of boutique clothing for my daughter, but I'm not going to spend $100-$150 for an outfit I can make for $20 worth of mats. But as you can see, $20 is still pricey for a dress. (ok I'm slightly obsessing on a focus, I'm going to move on)
Food, I love watching food tv. It's an absolute favorite around here. Rachel Ray, Alton Brown (have to have your science with your food ) and Tyler Florance are favorites here. They make the foods we are most likely to be interested in. We own a Rachel Ray cookbook that we cook out of a lot.
