Right, generally speaking most monitors/TVs/whatevers are going to have a set of resolutions that they are capable of displaying. If you have your heart set on a particular resolution, you'll have to make sure that it's capable first... though I've personally never been so set on a particular resolution that it's ever been a deal-breaker. It's probably easier just to set it to whatever's available.
As for response times, Bestbuy doesn't always list them... you'll either have to look it up online or check the product's packaging. I'd recommend a response time of 5ms or less.
