Well lets break it down shall we?
magery 120- 100% chance to caste, even if you dont use 8th level, your heals will be better.
eval 120- Its the muscle of a mage.
Meditation 120- Its your gas, with good enough mana regen the amount your gaining will mattter against one oppenent by that I mean you will (in theory) have more mana because you will have regained a decent amount by the time you have drained yourself.
Resisting spells 120- This is up for debate, I have many soulstones so alot of times I dont run with resist, this is something that I would highly recommend but wouldnt mind losing when needed.
Now as far as your other two skills go...
Weapon skill is a must for mages, without it there is NO WAY in hell you can combat a dexxer of sufficent skill. I say go with wrestling Simply because you get weapon skill with disarm, a godsend for us mages, and paralize blow which can also be very handy. Not to mention being able to weild an awesome scrappers. And dont forget chugging pots is uber.
Parry- Now they recommend you to have 80 dex to make it work the best, however I run with less and I still like it, its fun to swap up for resist when you know your fighting dexxers, even with low dex, its not hard to get a nice 25% chance to block.
Poison- Now it only effects your poison skill and your poison fields but honestly if your a veteran mage, you know poison is our bread and butter, I personally caste poison about 20 times during a duel and poisoning turns that spell into a killer, Not to mention since you have to be within two tiles, it will make dexxers think twice about getting near you.
Inscription- Very natural for a mage to have, an added 10% sdi on top of out alloted 15%, makes our spells very juicy indeed. Not to mention it benefits certain other spells. For instance you gain +5 on elemental resists, by casting magic reflect, and reactive armor at the same time, not bad at all, coupled with poisoning makes for a very offensive mage.
More later maybe
