Welcome to the forum. I am sure you will find a wealth of information, and many of us wil be overjoyed to help you. Just so we don't re-plow the sown field, maybe it would be productive for you to click on the search feature at the upper right of hte screen, and search in the seaplanes forum for keywords like "new to floats", "Newbie", "Getting started" ,"Float setup" etc. OR you can just scroll through all the pages of threads. THEN when you hit something that stumps you throw it out here and you'll get a pile of good advice.

One thing to remember: The biggest difference between land-based flying and float-flying is that Seaplanes don't have brakes. Anytime the motor is turning, it will be moving the plane. You can't just let it sit and idle like a dirt plane.
