Shaman Resto PvP need help

Hi guys,
i am looking for a guide about pvp (arenas and some bg) resto or i hope that somebody can answer on my questions:

1) i like to use Riptide and Lesser Healing Wave, - how should my build looks?
2) How should my gear looks? Salvations + Ringmail set?
3) What stats are most important? mp5>resi>spell power?
4) What about caps - hit rating and spell penetration?
5) Which gems should i use?

Thanks for answers, greetings

Did you check out these two handy guides?

WotLK [Guide] Resto Shaman PvP
WotLK [Guide] Random Resto Shaman PvP Tips & Tricks

Ofc, but 1st guide is from 2012 and its about healing Wave spec, i need Lesser Healing Wave, 2nd i read but there are only tips&tricks, it isnt guide :/

I like to Max out on HASTE. Considering Only 2 Healing Spells Is Instant: Riptide and Nature's Swiftness but they has a CD. Plus I Like Troll Berserking Haste Buff + BL Haste Buff. All together in PvP I stay behind the Damage Players Out of Range Of The Enemy And Heal Faster Than They Hurt Your Teammates. However I Prefer To only do this is Alterac Valley. Peace.
