I can't say much about (1), but I do kickstart my VM installs all the 
time.  My approach might not work for you, but here goes.

I put all my ISO images on an NFS share from my workstation, which I 
then configure on my EXSi boxes as a datastore.  I then put my kickstart 
files in a directory reachable via http.

I configure the VMs using VSphere and power them on.  Since I don't have 
a PXE server configured it pauses there, so I open the console to the 
VM, point the CD drive to an ISO image on the datastore, and reboot the 
VM using "send ctrl-alt-del," which then boots from the ISO image.  When 
the boot menu comes, up, I hit tab and append "ks=http://{url to 
kickstart file}" to the kernel line and continue from there.  The 
installation generally continues without much manual intervention from 
there, other than the "Initialize Disk?" messages.

There's a LOT more manual intervention here than I like, but there are 
constraints in my environment that will not allow me to stand up a PXE 
server.  I have been able to do this with the VSphere client on Windows 
(grumble!) and the web GUI via VCenter.

YMMV!
