They have also done away with the "Save for Web" option...what is now used?
No they haven't.
Adobe just did some thoroughly foolish and misguided "tidying-up" by moving SFW and hiding it in their new Export module.
Learn the KBSCs to go directly to SFW:
Mac: Cmd Option Shift S
Windows: Control Alt Shift S
Use those, and you will never have to endure a visit to the Export menu again!
