Probably not much difference in the bikes, at that price range. I don't know those specific models, but the market is competitive, and nobody's going to be able to put high-end components on a $350 bike. They may all be identically specced, at least for the major components. I'd look for the shop with the best service, or the one closest to my house, or the one that had a color I liked.
Be sure to get something that fits. I'm your height but about 60 pounds lighter (I've been as high as 270, though), and I let shops sell me things that were too small for years. Putting on a longer seat post DOES NOT help much--you'll wind up with a long reach down to the bars, which will make you uncomfortable, so you won't ride. If they try to do that, ask for a stem swap to raise the handlebars, too (they may charge for it, because there's not much profit on a bike like that). I'm assuming you're not in peak shape, so it's especially important that you be comfortable.
On the issue of weight (the bike's, not yours)--it's just not a factor in this case. There won't be more than a few ounces, maybe a pound of difference from the lightest bike to the heaviest, and in this case that's way less than 1 percent of the bike-rider package. You want something that won't break, not something that floats away on the breeze. I've been there, and it's better to be riding than fixing.
