Well to do the money like 99999999 money you first go to data/world/maps/campaign/imperial_campaign/descr_strat after you open that file you should be able to see something like this

campaign imperial_campaign
playable
there will be three romans faction listed there

just scold down to "start of campaign section" there you edit the denari from 5000 to 9999999999 I hope that help :)
