texture tweaking?

[visualnightmare]

i am new to maya and i was following the tennis ball tutorial on this site the modeling went smoothly but then i went on to the texturing tutorial and it is a bit vague i think i worked out how to get the texture on the ball but i dont know how to move the texture to line up with the model mayby i even used the wrong thing to put the texture on but any advice will be helpful.

I am working with polygons.
and i have a jpg image texture
