CB complete 1.3 and Worthy Heroes should be plenty, although hosting with both is redundant, I think.. I believe WH is included in CB complete.
Anyyyyyyway, you don't even need to enable them when you PLAY the game. You just have to have them installed. The only thing you have to MAKE SURE OF when playing a conceptual(ly) balance(d) game is that CB is ENABLED when you CREATE YOUR PRETENDER.
Otherwise there's a very good chance that when the game starts, it will say you are a cheater and give you an archmage with no extra magic and totally neutral scales, which you don't really want
