...so yeah...it was a newbie question. Figured it out eventually. I guess I just needed to declare the resource better. For those that care....

set CTime to (current date)
tell application "OmniPlan"
tell first document
set newTask to make new task with properties {name:"sillyTask"}
tell newTask
set camTask to make new task with properties {name:"Camera", starting date:CTime, duration:36000}
set bagTask to make new task with properties {name:"Bag", starting date:CTime, duration:36000}

--Declare your resource (person)
set personJamie to resources whose name is "Jamie"
set personSam to resource whose name is "Sam"

-- Assign the task to the resource
assign camTask to personJamie
assign bagTask to personSam

-- Set up your dependency
depend bagTask upon camTask

end tell
end tell
end tell
