Any suggestions on what to tell ATT to get IPv6 added to a current account and upgrade a 2wire router to 4wire with halfway decent performance and capability?
Any and all help would be appreciated.

The second half is easy. Do it your self. Turn the 2wire router into a transparent device and put your own router in doing the PPPoE for you. pfSense and M0n0wall support IPv6.
I am in AT&T territory, but don't use them for Internet.(I use the local cable company). But I know that several of my customers do have IPv6 connectivity already both on DSL and uVerse here in the Chicago Suburan area.

I have no advice on the equipment upgrade, but I was able to add IPv6 to
my account by visiting this page
http://www.att.com/esupport/ipv6.jsp
and running the compatibility test. Once it determined that I didn't
have IPv6, it offered to turn it on. A few minutes later, my router had
an IPv6 subnet configured. A co-worker pointed me to this link, and it
worked similarly for him. He's in the Santa Rosa, CA market, and I'm in
the Cleveland, OH market.

What is a “4wire” modem? Is that a Chinese knockoff of a 2wire brand? 
Or are you referring to a pair-bonded modem?
AT&T seems to only offer the pair-bonded device (in most cases, a Motorola NVG589) when you have their 45mbps “Power” service. If anything, you could always upgrade to the 45mbps service just to get the new modem, and then downgrade after you get the modem installed. The newer modems, including the 589, provide IPv6 support using 6rd.
The compatibility test previously mentioned will determine if your current device is capable of IPv6. The older equipment has firmware updates available that will provide IPv6 connectivity.
AT&T will do a bonded VDSL2 connection in cases where a single connection
isn't getting enough throughput. Also, be aware that the device may now be
branded as an Arris, but Tim is correct that it's normally a NVG589 for new
installs.

If ATT is still using 6rd then you don't need a hardware change to use
it. 6rd is like a 6to4 tunnel with special features. You can run it on
your router or other machines. Openwrt supports it.
Here is a brief how to, google for more help:
http://www.litech.org/6rd/
For ATT, basically, 2602:300::/28 (6rdPrefix/6rdPrefixLen) and
12.83.49.81 (6rdBRIPv4Address, which is an anycast) is all you need to
get it running. IPv4MaskLen is 0 (use the whole IPv4 address within
IPv6, but notice that due to 6rdPrefixLen being /28 (instead of the more
conventional /32) you have to do some one-nibble shifting, but the plus
side is that you do get a /60 in the end).
If your IP number is not static then your IPv6 address won't be either.
Of course you could always try 6to4, where the prefix is 2002::/16 and
the anycast relay router is 192.88.99.1. This will work if ATT
resolves the anycast address. Or you could set up a Hurricane Electric
6in4 tunnel.
So, with ATT residential, I think you get 3 half assed choices, 6rd,
6in4 and 6to4 (if they support it).
