Help putting together a parts list for new project

i use arduino turn on , off lawn sprinkler, first using switch , maybe later moving towards controlling via web connection.

i new arduino start trying put rough parts list. right have following things think need finish project:

- water valve solenoid (similar 1 seen here: http://www.adafruit.com/products/997)
- power supply solenoid
- kind of relay arduino trip in turn actuate valve
- switch
- few resistors

in head see switch being pressed, tell arduino actuate relay, activate valve.

are there major components missing here?

also, down road if plan control setup via web need use arduino ethernet shield? if want wireless need buy xbee? xbee replace ethernet shield or both required?

i appreciate guidance

depending on coil resistance, need transistor drive relay. simple tutorial sparkfun: https://www.sparkfun.com/tutorials/119

you need talk tcp/ip network. xbee doesn't that, mean either ethernet or wifi shield.
