I realise you mean you do move, just only when required. However, your statement here totally contradicts the tuskarrs comment. Either you move so much 8% actually helps your DPS a lot, in which case why? how? and where? Or you have put Tuskarr on your boots because you read it on the internet somewhere and it sounded like a good idea but don't know why.
I would recommend Tuskarr if you have no hit rating issue (otherwise ice walker is very helpful in reaching the cap). The minor speed increase can help a lot for survivability (avoid Icehowl on HM is the easiest circumstance that springs to mind). The crit rating on icewalker is nice, but not necessary, I try to maintain about 40% crit with Molten Armor at the moment so that I get about 50% of all casts criting (talents for the extra %). While many here downrate Crit strike value because it scales badly, I would agree it does, however it is not a scaling stat, it is a Base stat for a mage of any kind. If you think you don't need it, see what your DPS is when x% of your casts don't crit, I garentee it will be a large drop.
I would always recommend Reckless Amertrite and Purified Dreadstone for blue/yellow sockets. A lot of people stack +23SP gems in these slots, but I have seen a much large DPS increase with extra haste (my gear doesn't have a lot of haste so with gems I am about 500). In circumstances where you have lots of haste on gear, then certainly the +23 SP is the right choice, but be sure you have a sub 2.00second cast on Arcane blast before considering the move. 2.00 seconds is just a guide, but at this point you are touching the GCD with BL + Icy Veins. At 2.00 seconds you now have to decide if you split cooldowns or not.
