There are 3 modes to change jersey's color in each and every version of Photoshop:
1- You add a solid color layer above the Background (Jersey texture) and set it as Overlay.
2- Layer>New Adjustment Layer > Color Balance
3> Layer>New Adjustment Layer> Hue & Saturation
And man, thanks for the link on your sig

I didn't see it before
EDIT: In Photoshop Elements 2 there a colorizer button that will change the color quickly and will give you the shining effect my jerseys have
