For those reading along at home, none of those distinguish MRSA from a normal staph infection.
The primary distinguishing feature of MRSA vs regular staph aureus ("MSSA") is MRSA's resistance to oxacillin/methicillin. While you can find research papers distinguishing MRSA from MSSA on clinical grounds, I'm not familiar with any clinical distinguishing feature that is used in practice (aside from sensitivity analysis or PCR, which are laboratory techniques, not clinical ones).
