I think there are 15 luxury resources:
Wine, Coffee, Tea,
Spices, Sugar, Bananas,
Diamonds, Gold, Silver,
Dyes, Silk, Icense, Cotton,
Elephant, Fur
You should aquire Spices, Sugar, Banana, Diamonds, Dyes from Indonesian historical and core area. There is a Coffee resource hidden in Jakarta island, so discover guilds to get it.
Historically speaking you can trade for the other four, for example Silk and Tea from Chinese, Cottom from Mughals, Wine from Ottomans
The best alternative is to settle southwest in Philipines to aquire Gold and Silk, conquer the independent Pagan for the Tea and trade with Mughlas for Cotton or Ottomans for Wine.
If you conquer India or Indochina mind the English and French conquerors.
