You have to register the game online via steam, but you don't have to be online (if you don't want to) at any point after that.

From http://www.tweakguides.com/HL2_4.html

Do I have to have an Internet Connection to play Half Life 2: The short answer is Yes. If you don't have any kind of Internet connection, you cannot play Half Life 2. Steam requires online authentication of your Half Life 2 CD Key and it also needs to download additional files to activate and complete the Half Life 2 install before it can be played. There is no legal way around this - the CD Key must be authenticated online, and sharing Steam cached files with your friends is illegal. However once you've registered your CD Key and updated Half Life 2 you can play it offline at any time without having to have an active Internet connection - see below.

Playing Half Life 2 offline: Once installed, verified and updated online, you can play Half Life 2 without having to be connected to the Internet. To do this, follow the Steam Configuration instructions further below. Then whenever you want to play offline, make sure you don't have an active Internet connection and launch Half Life 2. When prompted, select the 'Play in Offline Mode' option and the game will load and play offline. For more detailed information, including playing offline on other machines, check this: Steam Article.

How Do I keep my game updated: Go to the 'My Games' section of Steam, and right-click on the games you want to keep updated. Then select Properties, and under the Updates tab for the game select 'Always keep this game up to date' under the Automatic Updates section. This is highly recommended so that you don't miss important updates. Alternatively, if you don't want Steam to automatically update games as updates are released, select 'Do not automatically update this game' instead. That way you can choose if or when you actually download and install updates. You can see all previously installed updates by clicking the 'View game name Update History' link.

one thing I've noticed *maybe it's just me* every so often Steam decides I need an internet connection to play offline, even if I select play in offline mode. it's a pain in the ass because I don't have perminate net access and I dunno why it should have to re-verify my steam account info more then once
