Reforge for mastery OR avoidance. Don't try and balance them, just go for one or the other. Personally, I would go for mastery as it is a more reliable stat. In terms of your damage intake, you should probably be using Death Strike more often since it gives you more than just the heal. I would grab up Blood Shield Tracker over at Curse or wherever you like to get addons to see when you'll get the best heal and how much of your Blood Shield is left (can't forget about that mechanic, especially if you stack mastery).
Unfortunately I can't see your armory since it says Battle.net is down, so going to have to assume some things.
First, going to assume you have at least this spec:

Which basically covers the essentials to get to 31 points in the tree.
Make sure you keep Bone Shield up, as it is pretty important for your damage reduction. Rune Tap when you use Vampiric Blood, (the glyphed version is better than without) and use VB pretty regularly since it only has a minute cooldown. It improves your DS heal as well, and I believe the heal from your bloodworms.
Most of your damage can be mitigated through your CDs, since AMS no longer requires runic power, and has a 45 sec CD, making sure you have Scarlet Fever and Frost Fever on your targets will reduce your damage etc.
