Plea for help for the unexperiencedFollow

First, a link to my talents.

I am looking for a good build to use with daggers. Something that does good with a group like combat daggers was something interesting I was looking at.

I'm mostly a solo player due to time constraints, which leads me to do more ganking helpless hoardies than I should. ( I get distracted a bit easily) However, I don't want to ***** over the little group play I enjoy for a full pvp build.

So any suggestions on what gear to search for/talent builds to consider would be great.

Also, what is the best way to gear up with more solo time than group time? Rep grinds? Battlegrounds?

Thanks for any and all advice I might get.
