I would first suggest that you only activate DRW/Hysteria before your rotation and not during. It tends to mess up your rotation and your damage potential you can do during the DRW is up is going to be slighted due to the fact you're going to hit with HS only twice before your diseases are off. That'd be my first choice. (If this is what you are doing, kudos but the way you were explaining it, it sounded like you were doing it during your rotation which really staggers your rotation as Blood's already tight.
Secondly, your hit is absurdly high. 490, jebus, boy! That's a lil overdone. You're nearly double of what you should be at (263 is the minimum, and around the 350s for the Spell hit cap.). Drop some of your hit, you're hurting your other stats by focusing on Hit so much. If you can get another trinket other than the Pyrite Infuser, that'd be a good start to look at.
Some of your gems are left to be questioned. The 24 stamina one is a big one that I go hrm at because you're basically getting no DPS increase. You have the crit one, so I understand that you want to get your meta gem, but you're better off having two purple gems (Just like your gloves have) than a purple and a blue. You'll get an extra 16 Ap out of it.
Some of your enchants are lower grade. Get that 10+ Stat, that's an extra 4ap (I know, that's just nitpicking but i'm giving you the lowdown

)
A note about your crafts... If you're actually looking to min/max? I dislike your professions. Now I'm not one to critique about professions (My JC isn't capped out for one..) But Alchemy will give you those extra flasks, yes, but Herbalism really does nothing for you other than feed your alchemy. If you want the best out of your DPS, you might wanna go the very very expensive route of JC/BS. But that would require you to drop all of your professions. If that's not something you want to do, then by all means you don't need to. However JC alone will give you something that most professions won't: 3 gems that give you 14 extra strength, which translates to 28 ap, which then translates to three times that amount, or 64 AP out of three gems. BS will give you two extra slots for 20 strength gems which is 80 AP on it's own. See where i'm getting to? You're missing on over 100 ap just from crafting itself. Now I don't know how much the extra flask gives you, but unless you're always chugging flasks, this static 100+ AP is enough to give you incentive.
Bout all I can see. Just keep at it, you'll get there. Practice rotations, know when to summon your ghoul even if he's not a pet at the right times and utilize Army of the Dead when needed.
