Lg shine question (cell phone)?

i just got it (first week of february)


1~and i was wondering if there was a way to plug it into the computer to get music onto it.


2~also where can i find covers for it (not a case, but like a new skin for it.)


3~is there a way to turn that thing that makes a check mark and says "message sent" or "keypad locked" etc... well is there a way to turn it off?


thanks for the help!!
