Is there anything taxes-wise that I can look into in order to reduce this cost, or another method that would allow me to net more at the end of the month?

The spreadsheet has the name of the state, the redemption period (the time the owner has to pay pack the taxes before you the lien holder can foreclose), the maximum interest rate you can earn for that state, the Bid Type (different methods of bidding are used), and Other information.

I see some people use comps or other methods.

There is a method called snowballing.

It would be a little disappointing to not get anything from using a method that seems to help other people land at least 1 deal a month from 160 letters while I'm sending out 300.
