Yeah OTTOL is right, the STAR is constant, it's just used as a transition from the enroute structure to the terminal area for increast efficiency and lower radio congestion. And yes, pilots *should* always carry all applicable charts for their destination and alternate airports. And, you'd only need to worry about STARS if you're a high performance aircraft, they usually deal with pretty high altitudes and such.
And speaking of carrying all applicable charts, just the other day when I went on an IFR flight for training, they requested a stop and go, and then I needed the approprate DP for the airport (You can deny SIDs and DP's, but since I was there, it was good experience, and luckily I had them all ready to go in the back seat) so it's always nice to have everything out and ready.
