First of all I do not recommend the GUI system-config-cluster for complex cluster configurations. Editing /etc/cluster/cluster.conf is easier and safer.
With the fence level settings you simply adjust the priority of the fencing agents. You can place your fencing agent on level 1 on both nodes. It is wise to add an additional fence level at least for fence manual.
Productive environments should use more than one fencing agent to avoid a single point of failure.
Your desired heartbeat network can be configured with changes to the /etc/hosts file. You should add the 192.168.10.x IPs and choose a descriptive name for them. That name then should be used in the cluster.conf for the hostname of the cluster nodes.
The heartbeating will resolve the correct IP address with /etc/hosts and select the right interface for communication.
Both NICs can be connected with a crossover cable.
