Yes, unless you've traveled outside the US after your H1B approval, your I94 # remains the same. About H1B transfer, you need to provide a copy of the newest (latest) I94 you received from USCIS. I might be wrong. This was my experience. I'm sure Santosh Giri or other immigration gurus here in Sajha will correct me if I am wrong. So just keep on logging in. Hope this helps.
