How to write rules for persistent net names?

To answer your specific question, add this to persistent-net.rules:

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="AA:AA:AA:AA:AA:AA", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="BB:BB:BB:BB:BB:BB", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="CC:CC:CC:CC:CC:CC", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="DD:DD:DD:DD:DD:DD", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth1"

Leave persistent-net-generator.rules alone. udev will not overwrite the rules you added manually but the generator rules will cause new rules to be added for new cards as usual.
