It looks like you want a wireless system. That will limit your selections somewhat. The L/R speakers only have 2" drivers and no tweeters so the sound, while better than the tv's speakers, will not be anywhere near as full as a driver/tweeter package. For a tv that size (even tho you're looking at a Vizio) I don't think the sound will be a good match for the video. Bose doesn't get a lot of love around here so I'd steer clear of them. Yamaha, Onkyo, Denon all make decent HTiB 5.1 systems around your price point. You don't have to use the side speakers (can always connect them later as your needs or room config changes) and your system would sound just fine as a 3.1. There would be some wires (R/L,C,sub) but there's always creative ways to hide those. The additional advantage if you purchase your system carefully is that the receiver can always be upgraded with better speakers, again as your needs or room config changes, and it will sound even better. Quality speakers can make an average receiver sound great, but poor quality speakers can make that same receiver sound bad.
