The easiest setup is TWGS, TWGold, and TW2002. The TWGS will handle running the trade wars sessions, a BBS is no longer needed. If you had tw2002 registered at one point, you shouldn't need to purchase codes for it again. You can contact John at
jpritch@eisonline.com in regards to that. As to multiple nodes, the are worthwhile. The game now allows multiple concurent connections to the same game, allowing for player interactivity.
