Since mods can't be bothered to come up with a decent answer I will give you what knowledge i have from playing the class.
PVP: I am going to tell you right now, don't bother. You will get destroyed in PVP. D/R's elites are made almost not worth getting soly because their damage boosting elite (Shadow Contract) doesn't give the same as Knowledge of the Earth (at 63% earth damage increase i think? While shadow contract is 40-45% dark damage increase.) On top of that Shadow contract cuts healing down by nearly half.
PVE: Well i will give you skills based on a level 50 character with all their elites, that way you have a decent idea of where to start. This is the rotation i use from logging on to first combat;
1. Pop up Savage Blessing, Concentration Prayer, Shadow Contract and Magic Turmoil. Then i spam Recovery to get myself up to 10 Natures Power points.
2. If its an elite or a boss, Speed Catalysis. If its a regular mob, i save it for later
3. After the mob is targeted i start with Poisonous Widow Embrace to start the fight
4. Get a Weakening seed on the target then start with your DOT's, Mother Natures Wrath, Briar Entwinement and Corrosive Poison.
5. Rockslide and Earth Pulse come next.
6. Switch between Earth Arrow and Poisonous Widow Embrace
7. Repeat.
Best way to look at it is this IMO; Keep up on your DOT's, make sure Weakening seed is on at ALL times (at level 45 it stops requiring natures power with the Curtain of Darkness elite) Rockslide and Earth Pulse are just extra little damage here and there but your main damage dealing skills will be Earth Arrow and PWE.
I would put points in PWE and Earth Arrow up till about level 35, get the Shadow Contract elite and dump ALL your TP into it to get it to 35 ASAP. Check the damage of EA and PWE and see how they compare. As your PWE level exceeds your EA level, you should be doing more damage as LONG as you have Natures power. Once that is expended, your damage drops by about a third i'd say.
If you happen to be playing on Artimes, that is the server i play on. I am rarely in game but i would happily log on to help you get yourself on the road to Druid/Rogue fun times.
EDIT: Not to discourage you or anything, Druids are not meant to be DPS unless you stat that way. I stated healer (Because i started as a D/W and added R later) so my damage isn't that great. If you stat for damage your outcome could be different, but until the Shadow Contract elite gets fixed, don't expect to top DPS charts or healing. You will have to find what works for you which may turn into abandoning D/R for awhile in leau of a class that is more "Party Acceptable."
