    The answer for Q1 should be switchport voice vlan #(from 1 to 4094 whatever option you will get), see the explanation below:

    Configuring Ports to Carry Voice Traffic in 802.1P Priority Tagged Frames
    Beginning in privileged EXEC mode, follow these steps to configure a port to instruct the IP phone to
    give voice traffic a higher priority and to forward all traffic through the native VLAN.
    To return the port to its default setting, use the no switchport voice vlan interface configuration
    command.
    Command Purpose
    Step 1 configure terminal Enter global configuration mode.
    Step 2 interface interface-id Specify the interface connected to the IP phone, and enter interface
    configuration mode.
    Step 3 switchport voice vlan vlan-id Instruct the Cisco IP phone to forward all voice traffic through the specified
    VLAN. By default, the Cisco IP phone forwards the voice traffic with an
    802.1Q priority of 5.
    Valid VLAN IDs are from 1 to 4094 when the enhanced software image (EI)
    is installed and 1 to 1001 when the standard software image is installed. Do
    not enter leading zeros.
    Step 4 end Return to privileged EXEC mode.

    backup Set backup for the interface
    block Disable forwarding of unknown uni/multi cast addresses
    host Set port host
    mode Set trunking mode of the interface
    nonegotiate Device will not engage in negotiation protocol on this interface
    port-security Security related command
