I have a question about what you should do with your deck after you do a reading? Should you term them all in the same direction or put them back in order or just put them away the way they end up?  

Whatever your intuition guides you to do.
I usually shuffle them and put them back in its box or wherever I store the deck.
Sometimes, I dont do anything; I put them back only to reshuffle when doing a new reading.

I am not a believer in these rituals. I believe in treating the cards respectfully. I talk to them sometimes after a reading; I thank them for a reading when I feel drawn to. I keep them  in a clean and safe place.
I cleanse them sometimes wtih my Reiki symbols or just say a prayer to dispell all previous energies.

I also don't believe in those rituals. I've read a lot about it and discovered that people do so many different things after they had finished the work with cards that there can't be only one true version. I just say "thanks" to the cards and then put them in a special box. Some people believe that cards must always lay segregated into major and minor arcana according to their numbers, etc or that they have to "clear" their cards by means of holding each card above the flame of a white candle. There is also a conviction that you should  knock on the table with the deck in order to let the negative energy go to the ground (if someone else touches your deck during the reading) but it sounds for me like a superstition! People do those things because they believe that if they don't, some bad energies will harm them.

I agree agata.
Although I keep my cards in a silky pouch, but that was not my choice; it was given to me and unless I find a better place to keep them, I will use that silk pouch.

I agree with Cedars and Agata. I usually thanks the desk and just  put it back in its box. I just clean it when it starts feeling "heavy" or when I feel it needs cleansing. For that I light an incense stick (usually sandal) and pass each card through the smoke. But I've only done this once a year or less.
