Advice to a new drinker

[CaptainHoneySmacks]

I turned 21 this week. Of all the new doors that have opened to me, whiskey is the one I want to try the most. Now, I have played Rugby for a couple of years - so I have had beer before. I expect that whiskey as well as many other drinks - will be vastly different. What whiskey(s) would you reccommend to me? I couldn't resist going into the ABC store(Its right next to the bank, ironic? I had to stop by pick up my new debit card and couldn't resist going in) and they suggested I try some samples before I bought a bottle. Someone was kind enough to make some suggestions and tell me a little about the history of each(Which I enjoy very much, I love the history behind things). He selected for me: Johnnie Walker Black Label, Jameson Irish Whiskey, and Woodford Bourbon. They are small sample bottles (managed to get them all for under 7 bucks too); Are they too small for me to get a taste of the whiskey? My roomie also bought me a small bottle of Jack Daniel Number 7. Is there any particular order I should try these in? How about different brands I should try? Any comments or suggestions, especially on storing them (Right now they are in the freeezer and have only been there one day - It was reccommended by the ABC staff to put them there for a day then try them) would be greatly appreciated! Thank you for reading.
