Regear question, any resident experts?

I'm looking to re-gear the taco. I bought the truck and it had 37" tires and was geared very low to match the speedo. I dropped the tires to 33" to save my gas from my commute. I don't know what ratio I have currently. So I've been jumping forum to forum and I'm thinking yukon 5.26 ratio is about what i need. But I'm looking to some advice before I jump into this. I also have to find out what to do with the front diff as well. Any suggestions would be accepted.

 

Truck is an 03 4x4 extended cab. 6 in fabtec lift. Everything else is bone stock.

 

If you plan on using 4wd you need the front regeared at the same time, they need to match ratios. Setting up a third is something you want done by someone who knows how.
