With the upcoming launch of Windows Server 2008 you'll start to see more resources related to SharePoint deployments on Windows Server 2008.
First to note is since RC0 of WS08, you need to have WSS service pack 1, and as applicable MOSS SP1.
To run Windows SharePoint Services 3.0 for a fresh installation after installing Windows Server 2008, install Windows SharePoint Services 3.0 x86 with SP1 (32-bit) or Windows SharePoint Services 3.0 x64 with SP1
You'll find a couple of references on TechNet related to deployment on Windows Server 2008 updated since RC0.
- Deploy a simple farm on the Windows Server 2008 operating system (Windows SharePoint Services)
- Install a stand-alone server on Windows Server 2008 (Windows SharePoint Services)
We're working on releasing a similar "slipstream" version of SharePoint Server SP1 which will include both the full version of WSS the WSS SP1 patch, SharePoint Server 2007 full version including the SP1. The installation will automatically include the service pack. In the mean time I recommend you look at Ben Curry's (SharePoint MVP) post on installing SharePoint Server 2007 on RC1 (instructions include how to put SP1 in the update). You'll hear about the download here when it's available. Martin Kearn has some similar instructions for including the WSS SP1 and MOSS SP1 when installing on Windows Server 2008. Note, when installing SharePoint Server 2007 on Windows Server 2008 it does require both WSS SP1 and MOSS SP1 be included when you install.
Upgrading from Windows Server 2003 to Windows Server 2008
After release you'll see more instructions on this topic on TechNet. We don't recommend you upgrade production environments until after the Windows Server 2008 release. We announced that this release was the last 32-bit version of SharePoint Products and Technologies at Tech Ed IT Forum 2007. I was exited to hear Steve Smith (SharePoint MVP) and Penny Coventry (SharePoint MVP) both of Combined Knowledge, have just released a paper on How to move a SharePoint Server 2007 32-bit environment to a 64-bit environment on Windows Server 2008. What a great document to get familiar with and to start including this in your plans.
SharePoint will have a booth at the Windows Server 2008 launch event in Los Angeles. We'll have copies of the new SharePoint Deployment Essentials guides. We hope to see you there.

SQL 2008 and SharePoint Deployments
The SQL 2008 team and the SharePoint Team are working together to make both products better and to ensure a better together experience. We currently plan to support SQL 2008 at its release. Expect to hear more about this as well. We don't recommend running production SharePoint environments on SQL 2008 with pre-release (CTP) builds.
