hi, im kinda noob but i can try

for the daggers, i have heard that you should get ALL dagger skills, but if you dont like some skills or you think you dont need them just skip them then, but i should choose all becuse it isnt much sp! and poison weapons, just choose yourself. you dont need. but if you have sp over or you want it Take it!. its a bit good to

hope it helped you, and thats what i have heard and think.
and stealth and stealth expert tree is good for pvp and that should you add to!
good luck!
