Quickbooks was the first accounting software that I used when I started in accounting, really easy to learn and the knowledge base is prolly the best out there since it is so popular with small business. Other than managing your inventory it can prolly handle most other tasks from your banking to payroll to invoicing/billing.
In terms of paying yourself you are prolly looking for a draw account, and ya basically you just use the business accounts to pay for personal expenses and pay income tax at the end of the year. Its the simplest option if you have no employees imo and are a sole proprietor, there are a few downsides but for a cash strapped new business its the way to go imo. That's assuming you are just on the hook for loans and not in a partnership with any investors, if you are in a partnership then you prolly need to pay yourself a salary.
