Despite the generous amounts of assistance I've bee getting from you guys, I've figured it out on my own.
@actor = $game_party.members
@actor.ws_exp = 700
0 being the index of the party member (0-3), 1 being the second weapon skill, "C" the rank I'm setting it to, and 700 is the amount of exp necessary for that actor to use that weapon.
Anyways, thanks again for the help. /Sarcasm
