Is this the right office for an SSN card, SSI, or Medicare?

Yes. There is no separate "SSN office" or "SSI office": Social Security number cards, Supplemental Security Income (SSI), retirement and disability (SSDI) claims, and Medicare enrollment are all handled at this SSA field office. Residents of a few metros (New York City, Philadelphia, Orlando and the Twin Cities) must use a dedicated Social Security Card Center for card-only services.

Can I apply for replacement cards or retirement benefits online instead?

Yes. In most cases, U.S. citizens can request a replacement Social Security card, apply for retirement or disability benefits, and check benefit verification letters online at ssa.gov without visiting the New Castle office in person. SSA says the online route is the fastest way to get a replacement card; offices cannot print one on the spot.
