What's a good place to store these tokens? My Ether Wallet? (Add a custom token there? Advice on how to do that?)
In my opinion Myetherwallet is the most practical and safe for this token at the moment. You can add TKR there like any other token in ERC20 standard.
You just need to use the following information:
Symbol: TKR
Address: 0xB45a50545bEEAB73F38F31E5973768C421805E5E
Decimals: 18
