I'm an newbee mom and I'm lost

[MoetheMom]

I just bought my daughter an mp3 player. It is going to be a Christmas gift so I have 2mo to get ready with the songs and all.
The mp3 I bought is a CRAIG model CMP1329. $50.00
It says:
256mp - 4 hours of music
mp3/wma compatable
DRM included
ID3 title
OK here are my questions:
1)Can I download music directly onto this thing? I don't have any CD's.
2)Which sites are good to download from and how do I know if they are compatible with this MP3 player?
3) Do the sites give you directions on how to get started?
I'm totally new to this and not realy that techno savvy. Any advice you can give would be appreciated. Thanks Moe
