Try doing trace Route to some stable sites, like DSLR.
Assuming good pings the most likely reason is your DSLAM was configured
incorrectly.

Short for Digital Subscriber Line Access Multiplexer, a mechanism at a
phone company's central location that links many customer DSL
connections to a single high-speed ATM line.

Well, sort of, but a multiplexer is a little different than just a "line", so
it could be that the DSLAM is overloaded with other customers, or your card at
the Central Office is defective, etc.

A communications device that multiplexes (combines) several signals for
transmission over a single medium.

But, getting back to your original question: "Anything else I should do to
trouble shoot the slow connection?", let me suggest that you test your
connection speed by downloading something locally to you. Like something from
verizon.net, like ftp, or Verizon's Usenet newsgroups.
Otherwise, you are getting the speed from you to somewhere on the Internet
instead of you to your Central Office. You need to download something local.
If you need help doing this, maybe their tech support can guide you with a
test file. Most providers have a test file for you to download locally with
your browser. If you have a 1.5MB line, your theoretical maximum download
speed should be about 182kB/sec.

Try using Verizon's own speed test page
http://www.ba-hss.com/speedtest/test750.asp, it's the "localist" for you.
Beware the page only gives download speeds (in bits and bytes), some people
like me
have incorrectly read it as download/upload.
Verizon has been known to misconfigure the higher speed DSL lines. A good
place to bring this up is at the newsgroup <0.verizon.adsl> where Scott
Brooks is Verizon DSL's official presence(?) and looks into this sort of
thing.
Hope this helps,

I have cable through attbi, with a 1.5MB line, and get 182kB/sec
sustained from their news server (when the news server used to work
properly anyway, now it times-out a lot, but that's an unrelated
issue.) I am only telling you this so you have a number to compare to.
I have dealt with BA/Verizon's DSL before and I can tell you that they
guarantee nothing. They say you will get speeds UP TO 1.5MB, but if
you get slower speeds, they'll blame it on distance.
http://verizon.net/learn/dsl_speed_demo.asp
Actual throughput (download) speeds you experience will vary and be
lower than connection speed after accounting for factors such as
length and condition of your telephone line; the condition of wiring
inside your location; computer configuration; network or Internet
congestion; and the server and router speeds of Web sites you access,
among other factors.
-------------------------
Notice, no insufficient speed issues could EVER be their fault. <g>

I'm not sure but I think you can access the whole family of Verizon
newsgroups <0.verizon.xxxxx> from anywhere but may be required to log in
using your Verizon username & password. Worth a try.

If you authenticate to news.verizon.net you can access it regardless of how
you connect.
Very convienient for me when traveling an at home. If DSL fails my router
falls back to dialup. Nice not having to change news and mail settings.

Glad you figured it out. It's unfortunate, of course, that BA/VZ
screws it up again.

If would be nice to be able to verify the service that you are
subscribing to without having to go through all this. Sigh.

Only twice? Geesh, I've been trying for almost 2 weeks to get up and
running and last night it appears that they finally found whatever the
problem was, and I'm up almost all day, but at a ridiculous speed (128K). I
miss my cable modem, but sob, can't get one here as we're subletting a house
without cable. Can you imagine?
