I'm guessing this line indicates a successful negotiation:
Jan  5 22:40:06 viammc pluto[31255]: "L2TP-PSK-NAT"[2] #1:
STATE_MAIN_R3: sent MR3, ISAKMP SA established

So yes, in all 3 cases of iPad, XP using external IP and XP using
internal, this happens. But in the XP using external IP case, xl2tpd
-D shows nothing. This was what happened when I didn't have 4500 open
when testing against iPad... opening that up fixed it and I then saw
debug output from pppd.

Now, how do I check if XP is upgraded, and upgraded to what
specifically? System Properties shows Versions 2002, Service Pack 3.

Can you answer this... for the XP using internal IP case, is the
traffic supposed to be encapsulated over UDP? I ran tcpdump on both
the server and laptop when using XP w/ external IP case, and didn't
see any attempts by either side to start traffic using UDP. But I'm
new to xl2tpd/openswan so I do'nt know if I'm doing something else

I also don't know if this could be related to my previous post where
ipsec requires a restart everytime I'm finished with a connection. In
either case, any suggestions would be great, I'm really at a loss on
how to get VPN'd into my network using XP.
