I don't know about arena, but absolutely no healing wave glyph for battlegrounds. You get almost the same hps and mana consumption (in proportion to healing) from the lesser healing wave, so you're better off with that one. If opponents actually allow you the time to cast a healing wave, you don't need the healing from the glyph anyway.
The stoneclaw glyph is nice. If you're feeling pretty strong, consider the frost shock glyph instead. It gives a 25% boost to the length of time you have someone slowed, which means you can shock, do a different shock after the shared global cooldown for shocks, then reapply the frost shock after the GCD, only a second or two after your original slow wears off.
As a resto, be sure to get the water shield glyph for your minor. Having to recast that 30% less frequently while under attack is a big deal for mana regen.
29 healer shamans typically choose one of two builds: 0/20/0 is the spellhance build. You get much more survivability, but you rely more on teammates to keep enemies off your back. If you plan to play like this, get a feel for how much mana you need. Others use an 0/7/13 resto build, choosing instawolf from the enhance tree and the reduced pushback from the resto tree. I avoid the healing wave talent in the first tier of the resto tree, since I don't use that spell in the 29 bracket, and put the 5 points into reduced mana costs for totems. That's not terribly useful either right now. I imagine it will mean more in 3.2 when you can drop multiple totems at once.
