what the best weapon and were should i spend my points?

It depends if you like to keep consistent damage, or hit big *( look for ee on your weapon(s) ).
Swords/ clubs are usually the heavy hitters, you want to shoot for ~ 100-120 dex with your gear on.
Axes I prefer on a fighter for the consistent damage, and go all strength.
It's entirely up to you though, there is no "best" weapon.

Always remember dex isnt as good without str... so dont go way over in dex make sure u get 100+ str.
