How often do I add this to the tank to get it cycled? Is it an everyday thing, or once a week?

Every day, per the instructions.

Instructions say "turn off uv/ozone" before adding. i have fluorescent lighting in a freshwater tank. should i turn off the fluorescents?

The reason to shut off the UV is because the product contains specific bacteria. In our tanks, we do not shut off the fluorescent lights, only the UVHere is a link to their website http://www.seachem.com/Products/product_pages/Stability.htmlNan

Will having this shipped to a currently cold/freezing location destroy the beneficial bacteria?

It should not, the bacteria is in a dormant state wont wont really be living till you put it in your tank.

How much would I need to cycle two 5 gal tanks?

As much as you can afford. I add it periodically can my tank and been cycled for a couple months. Like with large water changes or introducing new fish.
