After you commit those two sections to the configuration, any IPv6-enabled host on your network will automatically address themselves within that network block and be ready to access the internet via IPv6. If you're using Microsoft Windows Vista or Windows 7 and haven't disabled IPv6, you'll almost immediately see the "new network" dialog pop up. Testing should be as simple as hitting a known IPv6-only site. If you can get there, you're good to go. You're now running a basic, dual-stack IPv4/IPv6 network.
Other projects
After you're all set up, you can keep busy with a number of other projects. For example, if you have a few NICs you can toss into your router or a switch that's capable of VLAN tagging, you can allocate a /48 for your tunnel and carve out extra networks and configure routing and firewalling between them. Hurricane Electric has a great set of "certifications" that you can register for and attempt to complete -- many of which will require you to set up various servers (mail, DNS, and so on) on your IPv6 space and make them accessible to the IPv6 Internet.
If you get the time to do it, running through this process will bring you up to speed and give you the basic tools you'll need to survive in a post-IPv4 world. Instead of lagging behind the curve when the IPv6 hammer falls, you'll be ready.
