grinder
papers
bong (glass or acrlyic doesn't really matter although some people will try to be eletist and tell you the only way to go is glass)
pipe (glass spoon or simple metal pipe, same as above...)
a tray of some sort to work with your weed is nice also... i use an old chess board set it was a set that had lots of table type games (chess checkers, backgamon dominoes cards etc) it's wood about 1 sqaure foot and has raised edges
a nice box to keep all your shit together is a plus also....

*note* metal pipes/bowls (acrlyic bongs do have metal bowls generally) and they do have a taste near the end of the bowl (which is unpleasant, but should be noted any bowl near cashing isn't pleasent....)

glass is also tasteless
