If I have a court ordered drug and alcohol class to take can I still get a temporary license if I need it for work?

Until you actually fill out the PennDOT Restoration form, send it in to PennDOT with a check for the fee, AND, get your license back, you should not drive. In fact, in my county, until the DA sends a form into Harrisburg which shows proof that you completed all of your D&A classes, PennDOT will not restore. There is a provision for an Occupational Limited License in PA but it does not apply to DUI and DUI related offenses.
