I don't have the answer for the first part of your question, but the bandwidth utilization will be addressed for you here: https://www.cisco.com/c/en/us/products/collateral/conferencing/webex-meetings/white_paper_c11-691351.html#_Toc523258518

Keep in mind, as this document will tell you, the the bandwidth is a sum of both what you are sending and receiving.
