Second one looks like it's the Xen enabled kernel for virtualization.

Looks like it.
The second one is a PAE kernel - this is to allow you to use big memory on 32-bit systems. If you appear to be using less than all your installed memory (say only 2 Gig out of 4 installed), try the PAE kernel. As for that third entry, looks like it isn't complete, or is just a dummy entry (for a Xen kernel, had you chosen to install one).
