The last question, to make cash deposit buyer have to know only my name and account number? Or a type of account as well? (checking, savings). I have PNC and Citibank if its matter. Thanks!

Yes, do provide that info as one's required to tick on the appropriate box of the type of account on the slip when depositing cash into someone else's account and that's not really a sensitive info that you have to worry about giving up.
