I'm a bit late to the party, but I've very recently put some laminate flooring down myself.
The floorboards in my bedroom aren't the greatest, so I went for laminate in 12mm thickness, with a 3mm underlay (This did mean I had to cut off some of the bedroom door though), so I got away with not having to hardboard the floor. I just made sure floorboard nails were't raised, and the floor was clean (had to clean up a lot of dried plaster blobs off the floorboards!) etc.
With the laminate you posted it's very easy to lay - no need for a pull bar and mallet (the neighbours will be pleased at that

). If you are leaving existing skirting boards in place then get some wedges to put down to provide an expansion gap (e.g.

Then get some beading to put over the expansion gaps (which will probably cost nearly as much as the laminate!). A mitre box and saw are essential for this in order to get a decent join in the corners. How you affix the beading is also something to consider. I have previously used a hammer and panel pins (a nail gun would be much quicker and easier, but at a larger cost). This time I just used an adhesive, but make sure you glue the beading to the skirting and not the floor.
I personally laid the laminate in the opposite direction to the floorboards (mainly because my floorboards were crap and uneven). This caused more waste but makes sure that the joins of the laminate don't run exactly over the gaps in the floorboards (but usually advice is to lay end to end along the longest section, or if the room is square it should be towards the light source). Also if you are going to laminate all rooms, then usually people like to lay the laminate in the same direction in all the rooms to make it look better. I also needed a threshold that would accommodate the height difference between the laminate in the bedroom and the carpet on the landing (but if you are putting down laminate of all the same thickness this won't be an issue). I went for this kind:
https://www.diy.com/departments/colours ... 331_BQ.prd I cut my laminate using a jigsaw. This was very dusty. I think a circular saw would have been better, but I don't have one of those, so the jigsaw did the job for me just fine, although it was fiddly cutting sections for the doorway and wooden window panels etc

EDIT - I also second the use of knee pads. They are a must. I laid laminate a few years ago without knee pads and ended up with fluid on both knees, and they were very sore!
