Survey: 5 lines and campaign settings

Hello;
vicibox 4.0.3, vicidial 2.8-404a, Build 130605-0841, asterisk 1.4.39.1-vici, Single Machine, Vtiger 5.4
I need to do a campaign to be as following: Calling the people numbers, they will hear a message and they have an option to press 1 to talk with the agent.
I created campaign, and the routing extension is 8366, then I selected the survey method to be call menu and I selected the call menu that was created in the call menu.
I have some questions to be sure that I am in the right way:
1) I need the dialing to the numbers in the list to be automatic, can the campaign Dial Method to be INBOUND_MAN? Or what it should be?
2) As I have maximum 5 lines (ability to do up to 5 concurrent calls), but I need to use maximum 3 lines, how I can control this? Because I need to keep 2 lines for incoming calls to be answered by the agents.
Thanks for the help in advance.
Regards
Bilal
