Buddy,
I wouldn't expect much from the Rochester group in terms of application. So I doubt they would have the sanshou. They might, however, have some of the weapons forms. Still, after you learn the taiji it would be good to go and compare.
Here are some resources for you:
The first is the CPL organization homepage:

The vids at the bottom are pretty good. I'm pretty sure you don't read Chinese (I barely do) but even if you just click around, you should be able to see some pics, etc.

This link at the top has the different forms that the group now practices. The taiji is called the "99 form" here. Those links will take you to photos/vids of the forms. As you can tell, they have added several different short forms to the menu. I'm not sure why they did that. Padding the menu? It seems to me that ONE short form may be needed at the begining level but a 24 and a 36 seem a bit excessive. I haven't actually seen these forms done live so maybe they have value. I notice the Rochester group did something similar.
The second link at the top of that page is the competition form that they made up. The competition form exaggerates what makes the taiji special (as do all comp forms I think) so you can get a good idea of the "flow" that I've seen in CPL taiji.
Finally, I don't know if you've worked with Allen Pittman's people before, but I've met a few here in Taiwan and they are good people. Don't let the differences in the Gao style that they practice throw you off. This group is a branch of his students:

Both this sub-group and Pittman seem to be doing everything they can to get the complete CPL system preserved. I met a guy that Pittman sent here to get some forms that the group didn't have. And they are more martial than most other groups. You may want to shoot him an email and see if he has someone in your area.
After you learn the CPL taiji, you have to come back and post your impressions, ok? I would love to hear that.
take care,
Dave C.
