Best tips: Definitely tone down the cockiness, they don't know how to take it properly and are kind of crazy, I was punched (not too hard) in the face while in bed by a crazy naked lesbian who had never been talked to like that before. They are quite dominant and don't understand a lot of the humour and teasing we do back home. Like Roosh said, if you just want to get laid shut up and let them talk... even though you will hate listening to the shit they say since it will go against every moral fibre in your body, just nod.
Quite a few of the good bars and clubs mentioned in Bang Iceland have closed down (the book is quite outdated in terms of the clubs and bars it mentions). The most important of which was Bakkus where Roosh had the best time but has now disappeared, Boston is gone too. They come and go quickly here but I'll list the best ones which are around today below:
If you live closer to Laekjatorg (main square) the best place to pick up without any competition is Dolly -
http://www.facebook.com/dollyreykjavik A two level dance/bar venue with younger drunk girls very easy but often in groups with cock blocking guys, highly recommended.
There are a bunch of other clubs/bars (such as Austur and the places across from it) around Laekjatorg on the main street (Austurstraeti) which are full of older women who will flat out proposition you... to me these were a waste of time unless you are looking for a no effort flag... I will leave that up to you.
If you live around Laugevegur which is closer to Hlemmur (Secondary square with the bus terminal) there are several good places. Firstly Prikid
http://www.facebook.com/pages/Prikið-Kaf...ts&fref=ts which is the oldest bar in Iceland but also turns into a kind of dance club on the weekend. It was in this place where I was talking to a 7.5 and she was listening to me for maybe 4-5 minutes without giving any real ioi's like smiling or laughing but she stayed there and kept listening until she motioned to the bartended to come over to us, said something in Icelandic and he gave her a pen and a napkin and she then wrote down her number and name, presumably for a bang after the place closed and then walked away.
Another good club in this area
ON WEEKDAYS is the massively overhyped Kaffibarrin. Social circle is king here and there will be days where there are lots of guys. Also you will see the same sluts over and over again all week long here without much turnover. That being said it is the only place that is kind of happening on weekdays. Don't waste time here on weekends

Logistically make sure that you go to the ones close to where you are staying otherwise you are wasting time when it gets close to last call(this especially goes for saturday) so if you are staying near Laekjatorg, don't waste too much time at Kaffibarrin or if you are staying near Laugevegur, don't waste time at Austur.
