[Greenbuilding] Crawlspace

I'm getting ready to have some work done on my crawlspace....vapor
barrier on the ground & wall insulation. I'm calling a local company
whose info I got from this website to do an estimate:
http://www.basementsystems.com/crawl-space/crawl-space-vapor-barrier.html
I'll ask these questions when they come to do the estimate, but also
thought I would ask here (for unbiased answers). I have two
questions/concerns.
1. We had a small addition added to the end of our long, skinny ranch
house last winter. Imagine a long rectangle...we added about 15 feet to
the east end of it (a bathroom & extended bedroom). I had them finish
that new part of the house crawlspace in the "right" way (with a vapor
barrier on the ground & wall insulation), but since the rest of the
(old) part of the house crawl space is insulated in the (house) floor,
the new floor is cold. We knew we were doing this work soon-ish, and
are just now getting around to it. They knocked a people-size hole in
the end of the old foundation to allow access to the new part of the
crawl space, but I'm worried that the existing foundation (that runs the
width of the house) will be a long thermal bridge that never allows the
new end of the house to warm up. Thoughts?
2. Our plumbing runs are in the crawlspace and we had a bad plumbing
leak there last year. The kitchen sink drain became unhooked from the
main drain pipe (or was never hooked up well to begin with) and was
leaking water and some food waste under there for at least a
year--probably longer. Not helped by the fact that our septic was also
backing up, we think. It all got fixed when we did the addition and
renovated both bathrooms (and did work on our septic lines), but the way
we knew it was leaking was the smell coming from the crawlspace vents.
And we had a great deal of difficulty finding a plumber willing to get
under there and fix it. Anyway--if we have plumbing problems again--even
a small leak--with a vapor barrier down there, isn't it going to create
a swimming pool? How would we know?
I hate crawlspaces.
