For the PvP pack, it depends on what pack you bought. If the pack unlocked all of your skills across all campaigns, then the only things you need to unlock in PvE are the PvE-only skills in GWEN, Factions, and Nightfall (obviously they aren't unlocked by the pack since they can't be used in PvP).
Regarding the weapons, if you don't customize a weapon you can just put it in your Xunlai storage. Then any character on the account, including PvP characters, can take it out.
Also, this will eventually get moved to the Questions and Answers forum.
