Paying oneself from business account to personal account

I just started a business as an LLC and have set up a business checking account as well as a separate PayPal account. My concern is that I think my PayPal account was initially set up as personal using my SSN. Secondly, I will have access to both my business checking and my personal checking through one login with the bank. Will I run into issues when transferring money from the business account to my personal account? Do I need to create a pay stub using something like Quickbooks for generating payments to myself for my business?
