wether you use laminate or real wood, you will need a waterproof membrane as concrete soaks in water, also, i'd recommend some kind of cushioning to prevent innacuracies in the concrete floor from eventually coming through to the laminate / wood.
As for laying it, tools you will need are a jigsaw, a hammer, a special block to hit against the laminate (if you lay laminate), and also spacers, you will need to leave a 10mm gap between edges and the walls for expansion/contraction, thus i'd recommend new skirting board and lay the laminate before the new skirts.
Modern laminate is glue free and really is straight forward to lay, it literally just slots in the length of the piece, then you hammer the block on the side into the piece next to it, the only problem you should encounter is the very last piece, though, the claw on a hammer will help you here, you don't need to worry about it though as the skirt will cover it.
last but not least, there are 2 sizes of laminate, 6mm and 10mm, if you insist on laminate, go for 10mm, much more hard wearing.
hope that helps
