The best place to ask questions is on the ucb.class.cs61b newsgroup. We (the instructor and TAs) check the newsgroup regularly, and other students will be able to help you too. Other students will also be able to benefit from the answers. You should read this newsgroup regularly whether you post questions to it or not, so that you're not the last to find out about major changes to assignments and midterm dates.
If you don't want to make your question public, you may send email to email@example.com. Your email will be forwarded to the instructor and all the TAs.
For in-person assistance, here are our office hours. Most TAs will spend their office hours in 283 Soda, next to the CS 61B lab, or in the lab itself (277 Soda) when they are helping other students. You may visit any TA you find convenient, not just your lab TA.
