simply put, no you wont have enough resil from just pvp set pieces. you need some more pvp offset pieces like neck, bracers, belt, cloak etc. you also need some pve dps pieces to increase your dmg enough to where you can actually kill things. gem full arp and aim for 900-1000 resil if you are comfortable and usually have a healer. if all you can get is a ret pally teammate, i would suggest going into the 3s bracket and pick up a resto druid. ret/arms can work in 2s as long as your coordination is very good.
i would really suggest you read the complete arms guide and the fury warrior guide stickied to the top of the dps forum to get an understanding of pve dps as a warrior. maybe your spec is wrong or your rotation is wrong and can find out why your dps is low. it could also be a gearing thing if your dps gear isn't made up of 10/25 raid gear.
