Playing cards... Any brand will not do. Its plastic or nothing (preferably Kem - http://www.kem-cards.com/). We have been using the same two decks at my home game for over a year and they still look like new. They are a tad expensive ($27 for 2 decks), but are well worth it. In my opinion they are the MOST important part of a poker game. If I play at someone else's game I usually bring my cards just in case. A cut card is also helpful to cover the bottom of the deck.

Poker table... Quality green felt (speed felt as found on pool tables) is one thing but the type of felt you usually find pills/sheds like a cat. I still find green felt in my apt and we havent used it for 8 months. I have since moved to a piece of vehicle headliner (found at Jo Ann Fabrics) which I drape over my table, its a little padded and has lasted a long time and works well, at-least until I can build something more formal and appropriate.

Dealers... The button is usually the dealer in my game, if we had an appropriate 'Hold'Em Poker Table' we might do a single dealer but for now rotating seems to work well and keeps everyone attentive.
