If you're level 42, you'll probably travel near all of the places for Tarton's Wheel quest eventually. Any class can do this quest, although it's obviously easier for porting classes. The instant clicky from inventory is a great indoor/outdoor GCD resetter without the annoying effects of spyglass (or telescope, as Wrench likes to call it? isn't it nice to never be wrong?) There's no buff for protecting against dispel, and you have to have a target when you cast it, but unlike the other options its free. I use it on my druid and like it a lot more than my shaman's spyglass.

IVU, Shrink, Cure Poison/Disease pots are all worth considering. Keep a bag full of MR gear; you'll use it on raids but it's also handy if you wanna try to solo a caster mob (canni 2 shaman powder, for example).

Don't worry too much about the tash stick. Jousting or slow-tanking to land tash is almost certainly going to cost you more mana from hp loss, missed med ticks, and slowing yourself or the mob than you'd save from recasting a resisted spell. This is a very important strat at 60 when you've got Torpor and you're slow-tanking mobs anyways. Keep torpor up, slow mob, whack it with tash stick.
