What is an effective way to treat MRSA without medical treatment?

I know this isn't the most respectable way to get rid of an infection but, alas, thanks to the lack of US Health Coverage….this is what it amounts to.
Simple.
I know someone who may have MRSA, or an ingrown hair. Regardless, it appears as a pimple, and could me MRSA, so we are going to take precaution, and treat is as MRSA, which is more cautiously.

From what I can gather…these are the best steps to take care of MRSA from home.

1. Take a shower. Relax, soften your skin with warm water.
2. Throughly clean the infected area.
3. With latex gloves, drain the area, and "milk" it, so there is no more infection and puss.
4. Clean the area again, with warm soapy (antibacterial) water.
5. Apply triple-antibiotic ointment and cover with sterile gauze, and bandage.
6. Clean twice daily with antibacterial warm soapy water. and re apply fresh gauze and ointment.

Am I missing anything, because I imagine this would be the most effective way, next to actual medical treatment?
Help please.
