That's what you should be doing. There's no reason to get a new Access Token every time. Per the OAuth spec, you should probably code your app to handle an expired token gracefully. The spec states that tokens MAY expire -- Twitter currently does not expire theirs, though. However, that doesn't mean that they couldn't in the future.
