I was using a spreadsheet for bookkeeping and accounting.

Reading beginner real estate investing books not specifically about vacation rentals will still introduce you to things like due diligence, market research, property management (selection and managing), bookkeeping, working with contractors, etc.Kathy Fettke's Real Wealth Network has a lot of great real estate investing education.

Just make sure your bookkeeper is on the same page with the CPA. 

A first year attorney can easily pierce a veil without meticulous record and bookkeeping.  

We have 2 office staff members, office manager and book keeper.

Is the bank statements and property manager's reports solid to use for both the tenant management/property management tracking as well as the book keeping/accounting?

I just created a video with free software and instructions regarding how we do our bookkeeping and I just posted a free software application for how to analyze properties and a hundred more things for real estate.

I read both BP tax strategy books, and if nothing else, they've taught me the importance of good book keeping, tax planning, as well as getting a good real estate CPA. 

One needs to separate the concept of an "account" between just a category on your bookkeeping vs. opening another bank account.
