Rickorhino,
Since LANDESK manage deploying through a TASK. The only access you need to give to your techs (As Peter said) are "View" and "Deploy". This is not just for "Distribution Packages" but for everything you need them to deploy, like: Power Management, Agents Configuration (here in case you don't manage the agent installation using "Distribution Package"), Patch and Compliance so on..
I place all the packages to the "Public" container. Here is a picture of a what I am talking about.
I hope it helps,
Denyl
