How can I expedite process to obtain green card as a spouse of US citizen? I have applied in Phoenix I am told it takes 20 months!

The processing times of U.S.C.I.S. are an approximation, and many cases are called to interview before the end of the stated processing periods. That being said, even if the true processing time in your case is 20 months, U.S.C.I.S. would not expedite your case unless it was emergent. Obtaining a Social Security number can be done without having an approved case. If you file for employment authorization on form I-765 Application for Employment Authorization at the same time that you file the I-485 Adjustment of Status Application To Permanent Residence, the agency will normally process a work authorization within 3-6 months. With a work authorization card, you can apply for and obtain a Social Security card within a month.
