Hey Gale_,
You can certainly buy any deck you think looks the part. Cost may be something inhibitive and if thats the case you can start with bicycles or Tallys.
As for tricks, I'd say to jump into a book - Royal Road to Card Magic is a fantastic book and super affordable and contains everything you'll need to go from knowing nothing to enough to blow people away!
you could get both a deck and the book for less than $15.00 if you buy at the right places.
Best of luck and enjoy!
