As Rasmus notes above, there isn't too much in the way of Dennis Wilson materials in the bonus footage. As Rasmus states, there is a very nice photo album that has many excellent still images of Dennis. Some of these still pictures also feature Dennis' love Barbara Charren (see pic of him & her here:
http://denniswilsonforever.wg-net.com/families.html) It's hard to express just how cool Dennis is in these pictures. In my opinion, he never looked better. He's in top form and he just exudes coolness/hipness from every pore.
The director of the movie, Monte Hellman, a few difference times in interviews from '07, has some very nice things to say about Dennis. In particular, Hellman notes how unselfconscious Dennis was in front of the camera. (Possibly b/c he was so used to performing in front of crowds from working w/ the BBs?) Hellman's daughter, who was on set and has a tiny role in the film, also notes that she had a huge crush on Dennis.
For Beach Boys fans, it's really a shame that they didn't do a screen test of Dennis. This really would have been something to see, if you compare that possibility to the screen test that actually was filmed of James Taylor. In his screen test, James discusses music writing, his recent albums, touring, etc. Also, James performs one song solo voice w/ guitar; I can't remember the full name of the tune he plays, but it has the word "Railroad" in it. How unbelievable would it be to see Dennis solo performing one of his songs? The mind boggles at the possibility.
Although I have yet to listen/watch the film w/ either of the two commentaries that are included, that's about it for Dennis Wilson on the bonus features.
Even before I got into the BBs, I loved this film. It's one of the best films of the '70s. Even w/out any new insights into DW, this is still an amazing film in its own right and deserves to be watched/explored/enjoyed.
I didn't realize that the original cut of the movie was 3 1/2 hrs long, as Rasmus states above. They don't discuss this in the bonus stuff I've made it through so far. However, if true, it's really too bad that there are no deleted/extended scenes. Monte does discuss some deleted scenes in his intreview, however.

Drag racing east from L.A. in a souped-up '55 Chevy are the wayward Driver and Mechanic (singer/songwriter James Taylor and the Beach Boys' Dennis Wilson, in their only acting roles), accompanied by a tagalong Girl (Laurie Bird). Along the way, they meet Warren Oates's Pontiac GTO-driving wanderer and challenge him to a cross-country race—the prize: their cars' pink slips. Yet no summary can do justice to the existential punch of Two-Lane Blacktop. Maverick director Monte Hellman’s stripped-down narrative, gorgeous widescreen compositions, and sophisticated look at American male obsession make this one of the artistic high points of 1970s cinema, and possibly the greatest road movie ever made.
