Not sure, but here's what I can tell ya...
The King Leoric Arm would be my choice for sure.
Frostburns might be your best bet.
Shouldn't need much strength if you use a Mage Enigma. Pretty sure marrows give some str...not sure about the rest.
Use 2x SoJ.
I'm not sure what skill tree a Darkforce gives to...Curses maybe...either way, check the stats on one - might be better than a Homo. Although homo is a lot cheaper (on NL anyway).
Max Skele Mage.
Since you're going for the most damage you can get, max Amplify Damage.
1 Clay Golem (Pre-requisite).
1 Golem Mastery (Pre-requisite).
Not sure if you want Revives or pure Skelly's....so either Max Revive or drop some more points in a golem. Make your Clay Golem better, or go for a Fire Golem.
Max Summon Resist. Max this last, after you decide your golem.
One thing you left out, a merc. You have many choices here, I'll attempt to list some of them...
First off, to get it out of the way; an
Act 3 merc.
Now if you don't know about them, you may be asking "What? Act 3 mercs suck balls!". Well, they can wield (equip) shields. What gear would it use? Dream helm, Dream shield, and an eth archon Bramble. Also I should add right now, no matter what merc you decide upon, PUT AN ETH BRAMBLE ON HIM/HER.
The nice things about this merc.
Dream helm+shield = Nice holy shock aura, not only for you and your merc - but also on your summons

.
In my opinion, Bramble is a necessity to ANY summoner. Thorns help more than you think

.
Another choice,
Act 1 Cold Arrow Rogue (aka bow merc).
Use an eth Ice bow. I just thought of something... If you put your Ice in a GMB (Grand Matron Bow), do the +skills from the gmb add to the skills that Ice give you? Find out about that. If they do, use an eth +3 GMB (probably hard to find =/) to make your Ice. If not, just find an eth bow that has nice damage. I would say use the fastest bow you can get, but you're going for the best damage you can get

. For the helm...well, if you find out that the +skills from your mercs other items DO add to the skills Ice gives her, use an eth Valk Wing. If not, get an eth Vampire Gaze. For the stats on the gaze, if you can't or don't want to get a perfect one - get a "half perfect" one. What I mean by that is; Either get one with perfect DR, or one with perfect LL. Gotta go one way or the other. Socket your helm with a 40ed/Lifer. I don't know how much life you can get on a 40ed jewel, I found a 40ed/7lifer last week...if you can't get any higher than 20 life with 40ed, just get a 40/15max. For the armor, as always, eth bramble.
Nice things about this merc:
Holy Freeze aura. On you, on your merc, and best of all - on your summons.
Cold Arrow. Slow down the beefier enemies so your summons can pwn that much easier.
Act 2 mercs.
Since there are a lot of combos you can make here, I'm not going to go too deep into discussion (at least not tonight). I'll just list some gear combos, and if you have questions I'll answer them tomorrow or sometime soon.
Combo 1
Pride
Bramble
Dream
Combo 2
Infinity
Bramble
Dream
There's more but I'm hella tired and still hungover from this weekend...maybe I'll post more tomorrow.
EDIT: Damn that was a long post.
