Unless you're looking at your TV from a really close distance, upgrading might not make much sense. It's a small TV and you won't be able to notice the difference unless you're really close to the TV. Of course a new TV might have visibly better image quality even otherwise, but you won't get the benefits of the better resolution.
You should get at least 37" for 1080p.
