Configuring VM with Multiple Cores

I have a gulftown 6 core processor, running Windows 7 as my host OS. I'm new to VMWare and have a few questions bout using multiple cores. I'm installing Ubuntu 10.4, the 32 bit version. 
 1. If I specify 1 processor with 4 cores for the virtual machine does that mean Ubuntu can use 4 of my cores? 
2. Are cores reserved explicitly for vmware or are they shared with my windows processes? 
3. When configuring a new vm I can specify the number of processors and the number of cores. From a vm perspective, what's the difference? Both are essentially multiple processors. 
 Thanks in advance.

1. Yes
2. They are shared
3. You specify the number of vCPUs (Virtual CPUs). In the physical world 1 vCPU = 1 Core.

    I'm new to VMWARE. My question is how I can set VMWARE test lab ? so that I practice to work on VMWARE, as all VMWARE jobs required experience.
