Intel wireless card and bluetooth

I ordered an E1505 and it is comming with an Intel wireless card. It also is going to have bluetooth. Is this one card or two seperate card in my system. Can some explain how these two work. I am familiar with wireless nics but not with bluetooth. I was also told I could use a bluetooth compatible mouse. Any ideas where I could get one. Thanks...
