nope

O.K..  I see from the following press release that the tanks are contracted to Alcatel Alenia Space in Turin, Italy.

http://www.home.alcatel.com/vpr/vpr.nsf/DateKey/18042006_1uk

Alcatel Alenia Space (probably just Alenia Spazio then) won this work in 2001.  The move from Pueblo didn't happen until several years after that.  Who built the tanks prior to 2001?

It's the Mobile Service Tower(MST).

Answering my own question (the answer is Boeing at Huntington Beach), with info from the following abandoned web page.

http://216.239.51.104/search?q=cache:i5wdqt70wkUJ:www.alespazio.it/space_infrastructures_page.aspx%3FIdProg%3D43+%22delta+II%22+tank&hl=en&lr=&strip=1

"Since the 1980s, and exploiting the know-how and technological capabilities deriving from aeronautic and space applications of Tungsten (TIG) welding, Alenia Spazio has developed a production line of a small series of tanks in special steels for the liquid propellant of expendable launchers. With the termination of the medium European launcher Ariane IV, for which the company delivered 482 tanks over a period of 20 years, Alenia Spazio is continuing the production line through a major commercial contract with the US company Boeing for the tanks of the Delta II launcher. Alenia Spazio produces the (single) tank for the second stage which was previously (up until 2002) built at Boeing in Huntingdon Beach, California. The present contract (a unique case of a non-US company working on an American launcher) is for the supply of 22 tanks. However, given the long life expectancy of the vehicle, there is a strong possibility for other orders in the future. Tank production began at the end of 2002 after a successful development and qualification phase and 6 tanks have so far been delivered."

The Mobile Service Tower should be retracted within the next hour.

That is the MDC (Mission Director Center).  The LCC is not shown.  It won't be manned until at least L-270.  the spacecraft control center is in the upper left.
The MDC is where the Mission Director, NASA Launch Manager and other high management reside

The Mission Director's Center will start to be manned about 30 minutes prior to start of Terminal Countdown at 5:38 pm EDT(2138 UTC).

European experts have played an integral role in developing and building the instruments on NASA's STEREO spacecraft. This exciting new solar mission will allow scientists to build on the work of the ESA/NASA SOlar and Heliospheric Observatory (SOHO) mission.

It's the fuel meter that measures how many gallons of RP-1 has been loaded into the Delta II core stage.

Looking forward to a great launch.  What altitude will these satellites reach at their high points?

Say what??  An AU is an Astronomical Unit, which is the distance from the Earth to the sun (93,000,000 miles)!!  That can't be right.

Exactly! The probes will be orbiting the Sun. One will be preceding the Earth and the other one will be following it.

See that thought crossed my mind after I posted but I was thinking these were Earth-orbiting satellites.  Cool to hear!  How far out from the sun will they be?

The distance from the Sun to the probes will be ~1 AU. I don't know the distance from the spacecraft to the Earth. See these animations:

http://www.nasa.gov/mission_pages/stereo/multimedia/getting_there.html
http://www.nasa.gov/mission_pages/stereo/multimedia/heliocentric.html

Something happened after I reinstalled my Windows and now I cannot watch the animations in both MOV and MP4 formats. Hopefully you will be able to watch them.
