rjhtamu, you are confusing racial traits with skills. The "proficiency" you are seeing means that as a Human, you get a bonus to using swords.
To see your actual skills, don't click on "Spellbook&Abilities", instead, click on "Character Info", then click the "Skills" tab at the bottom of the paper doll window that pops up. This will list all of your skills and at what level you are at with them.
You can't use swords because you have not yet trained in them. Go to Stormwind and ask a guard for directions to the Weapon Master, then follow the arrow/flag on your minimap.
Also, remember that you are playing a beta, what's not explained in-game will likely be talked about in the instruction manual and/or tutorial that you will be able to use when the game is live =)
