I use a very similar build to Grimm's so you'd be well of using that or the one I use (can check my armory in the sig). Just some minor differences in where I put extra points. If you're new to tanking, I'd suggest going with Morbidity like Grimm's so that you have more room for error to drop down a fresh DnD if things get a little out of control. I put my points into epidemic just because I like the looser rotations it provides and I don't use DnD as much as I could.
I think your unholy build would have some threat problems. I'm no expert in unholy but I think something along the lines of
9/10/52 would work better. I'd like to find one point to push into maxing bladed armor, it might be best to take it from Ebon Plaguebringer. I'd also like to maybe get a few extra points to stick in Ravenous Dead for more strength (turned into AP), but that's where my inexperience with the spec comes in. The key is to get some more expertise (and damage) through Rage of Rivendare for Scourge Strike and other abilities so you're not dodged/parried more than you have to be and to enhance the damage of SS through the extra disease provided by Crypt Fever.
You don't need a ghoul to tank even though I imagine its cool to have on always following you around (I'm frost so I have yet to have that pleasure).
The reduced cooldown on Death Grip is only useful for PvP and Spark pulling (but if you're tanking, you're not grabbing sparks). Dark command is a short enough cooldown, and you have a very short cooldown on DnD too which is more than enough to fill the gaps between DG cooldowns.
Corpse explosion isn't needed so much for tanking, you have other uses for that runic power.

I have tanked unholy for a while and this is my build :
http://www.wowhead.com/?talent#j0EZ0xxZfxhIx0zxcV0coux:MdA0mVI have no aggro problems what so ever. In fact, if I was hit DnD every time it came up I can make immense amounts of threat. However, i have no need for it as my threat is already big enough.
I'd recommend you try out unholy as well, I enjoyed it much more than frost

Wandering plague is pretty much useless, tansk have a VERY low crit %.
AMZ and magic suppression are nice but highly situational. Generaly AMS is enough to survive.
I did not take dirge as i have glyph of UB which means i need less RP
