Well as the original poster, I ended up with something like
guns 100
energy weapons 50
lockpick 90
repair 90
science 70
speech 80
sneak 70
melee 30 (wasted points)
unarmed 90
everything else n00b
preferred kit: silenced sniper, all american (all round), that machine (COD flashbacks), pushy/ballistic fist
Even by around level 22 it was getting too easy lol. Sniper rifle + decent sneak = easy mode. Lets not even mention unique powerfists. By the time I got power armour I was on full autopilot
I ended up having a lot more fun with fists than guns but its not always practical to run straight at a minigun lol.
With above build, I could usually nail the non violent way in 90% of quests even if a magazine or two was involved.
