another easy way to set default launcher is download "home switcher" from market. in order not to "lose" your launcher pro or other apps which supposed to be place in /data on Doc Rom due to factory reset, just extract the apps and place it into the Doc Rom's system folder (Doc_XXJPO_v7.6.2.zip\system\app). when you flash the ROM using cwm, it will be placed into system folder, meaning even if you factory reset, it will not be erased. btw, the launcher pro comes with Doc Rom is not the paid/full version, hence i placed it with the paid version.
