I'm assuming that when you say PvP you mean battlegrounds and not world PvP. There are no builds that are perfect for both PvE and PvP. Generally people will suggest straight combat swords or a mutilate build. Both of which are decent at both (instancing and BGs). Combat is built around sustained DPS (better for PvE), Mutilate more of a burst build (better for BGs).
For some dedicated PvP builds check out
Theo's PvP guide.
As for your build, move the two points from Nerves to Vitality. I've never noticed any major problems not having MoD in my combat builds when in BGs, but that's really up to you I guess. If you position yourself properly you shouldn't "need" it. You might also move Imp. Evis points to Ruthlessness.
Happy hunting.
