November in Indian Creek is PHENOMENAL. You can most definitely climb there during November. I usually squeeze in at least 2 trips during the month. Thanksgiving (4th Thursday in November) tends to be the closing trip of the Creek season for most people, as it does get chilly after that, but I've climbed there in December as well... as long as the sun is out and the wind isn't howling, it's climbable there.
As for people to climb with, definitely. You can post up on the message board or just walk around the Bridger Jack camping area. Definitely also see if you can get some folks lined up beforehand to meet you there. Climbing at the Creek can be 'interesting' in terms of having enough gear... think of Incredible Handcrack, which can eat up ten #2 camalots (#3 Friends) with ease. Same goes for other cracks and their respective sizes. So it's important to pair up with someone that has access to a sizeable rack. Again, Mountainproject.com is a great place to get partners. And don't miss Castle Valley on your way in/out of the Creek... Castleton Tower is not to be missed.
