You should try as many types and brands of whisky as you can to try to discover what you like and don't like. Personally I don't like bourbon very much, but I still try new releases or brands when offered.
You don't need to store the whisky in the freezer. Any cool dry place out of direct sunlight is fine.
As for how to drink your whisky, my recommendation would be to sip it at room temperature in a Glencairn glass straight up, or with a splash of water. Of course, you should enjoy it any way you want.
Post what you like and don't after you try several whiskies and we can make some recommendations for you. An upscale bar should have a good supply of whisky and bourbon for some serious sampling.
