Dark Blast / Darkness Manipulation build advice

[IneptAdept]

I am second guessing myself on several skill picks, so I could use some suggestions for improvement. 

Because Blackstar, Midnight Grasp, Dark Consumption, and Soul Drain are all being in melee range, 

I have taken Smite and Shadow Maul.  Should I get rid of one of those and take Moonbeam instead?

Also, should I add or change the slotting on Life Drain to do more damage?  Thanks for advice, and

if anything else comes to mind, please mention it.
