Looks like a solid team as far as starters go. I like to keep a QB on my bench in case of an injury, which has happened to me a few times. Both RB and WR thin out a bunch on the bench, but you probably don't have many options at this point, just keep your eyes out for up and coming guys. Cadillac is a good option who was available in my 12 team league this morning. To me the only guy I would throw away is Rice, maybe to have Newton, Henne, McCoy or Grossman available to you if Romo goes south. All 4 of those guys are still available in my league. I would keep an eye on TE's as well, Pettigrew isn't horrible, but guys are always climbing the fantasy pts charts early in the season.
Thanks for the comments on mine....Good luck.
