The best thing to do is get 3 cables and a wetgear, the rest of your PP should come from .moar files, there are also 2 books for hackers that give 25 and 50 PP.

As for stats just dump everything into frugality in the beginning and get your upkeep up to a manageable level, also some ego helps. After you get the cables and wetgear talk to haxelrose and put points into offense.

In my opinion, hackers seem pretty unfinished right now, and we might be getting some new skills in the future to cope with our weak attacks
