Payment option when selling something

[sloppie_00]

I'm not sure if this is a proper place to ask question but I'm selling my wow account and I just need to know the safest way to accept payment from the buyer to avoid scamming.

If I want to use Paypal then what info do I need to look out for? Any certain info need to be matched?
What type of payment should it be?
I've heard some people ask the buy to send as Gift payment to be safe. Is this safe?
Can you give me the step-by-step version of the process like what info they need to give first before I can give our my info?

Many thanks
