Reveal Map
When you save the game, name it "multi". This will reveal the map and allow you to see what other civs are producing.

Unlimited Gold
First make a backup copy of the file script.slc, which is located in:
..\ctp_data\default\gamedata

Then open up the original with any text editor and add the following lines:

trigger 'DOR_T_Give_Gold' when (IsHumanPlayer(g.player) && (player.1.gold<=200000))
{
AddGold(g.player,1000000);
}
