newbie confounded by hooking up GP2 sensor and MP3

yikes! i've boldly jumped in over my head!

i used to do more raw electronic projects, and thought i could work my way through an Arduino project for an art installation

i understand the basics so far, but often find the forums applying to this level more confusing with the language :-?

could someone take pity on me and lend a guiding hand?

where i'm at: Arduino functioning and playing nice with basics like the Melody exercise

my demise: i have a Sharp GP2 sensor that i want to connect...ok...but then, i would like that sensor to use Arduino to trigger a sound file when it senses folk coming close to the sculptures

does anyone have a recommendation for hooking up an MP3 or other player to the Arduino for this purpose?

and can anyone recommend/share/know where to find/how to build code for this project.

i ask a lot, but will send you buckets of good karma and a thank you in the project presentation

all the best,
Mai

Well first, the mp3 shield!:

Take a look at the links on the left for more information
http://www.ladyada.net/make/waveshield/

Now, for your sharp sensor, there's a couple things you're going to want to get a simple grasp of, first, the map function, to make sure the readings of the sharp, stay within a certain range.
And also in this link, is going to be the SwitchCase function, what it does, depending on what value the example gets, it maps it down into 4 values.

This tutorial should help alot, and then the MP3 part is all up to you! (I have no experience with the shield:P)

But best of luck, hope these help:)
