What do you do to protect the legal integrity of your LLC?

[Account Closed]

I have created a LLC for holding a piece of rental real estate in Florida. I want to make sure I take the proper steps to keep my LLC as a separate entity then myself, what should I do other then the steps I have listed below?

Also- I purchased the property in the name of my LLC, but used my personal bank account to physically wire money to the title company. Is this ok? How should I record this transaction?

Things I think I should do:

1) Conduct regular meetings and record minutes
2) Use a Florida registered agent
3) Keep a separate bank account for the LLC and only use it for business expenses
4) Hold a operating agreement
5) Do I need to use "Quickbooks" or other professional accounting software to record expenses/revenues?
