When I take the tiles off how will I know if there is a vapor barrier?
I also read in a topic that you can use plastic for a vapor. What kind of plastic is it?
I also researched a vapor retarder. Where do I purhase that? Lowe's seems not to supply a vapor retarder. I installed a laminate floor in my house in a 14' x 28' room but the subfloor was plywood. I just don't want to make the floor buckle without using the right products.

first, let us know the manufacturer you are using.
6 mil poly film works great but the pad that comes with the floor may have it.
removing tile requires little more than a hammer and such.
if the floor is way out of level you may need to use a self leveler, or trowel the stuff on if it's not too bad.
read the manufacturers guidelines when it comes to flatness.
usually not more than 1/4 inch up or down in a 10 foot wingspan.
