What is the best way of removing that black asphalt like thing? Paint thinner?
RWebb,
there are lot of stores and I already visit several. I ask here because I know there are many people here do things much better than the usual installer out there. All stores are telling me to simply glue wood down to concrete, and float technique on laminate.

First off that black stuff (I had tar paper under old tile), all dirt, old adhesives, all of it...needs to be completely removed. I demo'd my own floors and installed wood but I hired out a team of guys to clean/grind/strip the floor to virgin slab.
You're also going to need to verify the floor has no low spots that will need to be filled. Simple test for moisture is to tape a 3'x3' piece of plastic sheeting to the floor for a day or two. If it pulls back moist then you have an issue.
How many sq/ft are you talking about?
