There is no other launcher. Your options are to first install the new launcher and activate it. Then delete the launcher2.apk from the system/apps via root explorer or abd. You can also make the changes prior to flashing within the zip itself. Then reflash. This Rom doesn't delete your data so you could install right over top.

You can also click Thanks over at XDA in mammon88's tread. He put a ton of hard work into this thing and deserves all the credit.
