EXS 24 Logic Sampler Users Group

I recently purchased apple's production suite and was told that 
logic pro 7 was the new wave in digital audio workstation.  I did 
some research and every audio person I knew gave it rave reviews.  
Only thing is, I am a relative newcomer to the audio field and don't 
know the ins and outs of sampling and midi interfaces.  I purchased 
a usb midi keyboard that gives me realtime access to all of the 
instrument plug-ins, but I don't know how to create my own sampler 
instruments.                                                         
      I am extremely inspired by music that incorporates any number 
of samples.  Especially highly experimental music.  I would like to 
match my "self recorded" audio(bad guitar, worse singing) to my self 
recorded, self produced fx libraries.  I have created many tones and 
noises which i would love to incorporate into a sampler instrument 
to be called upon in real time or in sequenced midi.  How would I go 
about this?  
    If too much of an explanation is needed, don't worry yourselves 
and recommend another website/book that may help put it in a 
somewhat 
lay-man's perscpective.  

thank you for at least reading this message and perhaps having a 
little laugh at the new guy.
