That is a broad topic my friend. If you are new to LANDesk, you might want to start with the LANDesk Landing Page: http://community.landesk.com/support/docs/DOC-7423 .
There is a link specifically talking about deploying Office 2007 but you might want to start with the basics...like adobe reader first. Or a simple single exe link Mozilla, just to get your feet wet.
The core needs to be configured properly - scheduler service, preferred server, IIS, etc... If that's all correct, then start with setting up a distrubution package. Again, too broad to discuss here. Use the link to get started.
