For long fights to get the most dps I like to open with Daggerfall (combat ability) then follow up with 3.0 right click. I have the 3.0 on a hotkey so I can hit it right after the first backstab.  You still have to wait for the next oppertunity to backstab but the reuse timer starts when you cast not on when you actually use it and you have 30s to use it.  I usually follow with a 2nd 3.0 right click at the 30second mark. As soon as it goes off I burn duelist. After duelist is up I use frenzied stabbing.  Throw in a 3.0 click whenever no discs are up.

Other tips:
Sneak can be used to run behind mobs even if they can see through Shroud of Stealth (first AA a rogue should ever buy).
Mobs turn slow so you can dance around mobs to get a shot at the back when soloing.  Practice a bit and you will get good at it quick.
Deadly Precision which has a short reuse timer (5mins or so) also is right click on 2.0 or 2.5 can't remember which adds a small bit of dps (should lower miss rate a couple %) Also use SoF or SoD client for extra attack.  Using said clients + deadly precision I parse 98% on target vs 96% on titanium.
Nimble (dodge for 15s) has its uses if you are waiting for a heal.  Normally counterattack is a better option however nimble reuse is half that of counterattack.
Always verify that sneak actually worked before taking off running into a crowd of mobs.
Casting spells doesn't break sneak hide on here. You can often single pull mobs by using a clicky especially from behind.
Looting corpses breaks hide but the button doesn't reflect it.  If you are carefull you can sneak behind a mob and loot a corpse it is standing over as long as no other mobs facing you are close enough to agro on you.
Rogues have a smaller agro footprint than other classes.
For Escape to work you have to hide immediately after using it unless you are out of agro range of the mobs.
You must be standing still to hide.  The nimble evasion AA doesn't work on here.
Rogue CoH (corpse drag + rez clicky) is quite usefull for skipping trash in LDoN etc.

The brown dragon that is shown I believe is a respawn.  There is a spawn point real close to where they were standing around the corner.  At the 0:06 mark you can stand at the shadow on the rock and it will block the aoe.  If the brown popped it doesn't suprise me at all that it agro'd them as thats what will happen every time.  I should know as I've had it pop on me while I stood there waiting for the AOE casting mobs in camp to die.

As far as Casual Fridays in addition to myself and Morphius you can also send a tell to Fracturer in game.

Usually one of us is on.

Also note for anyone that is interested in joining we will not tolerate any kind of misbehaviour in the guild.  While it is easy to get in to this guild it is also easy to get kicked out for being rude, immature, etc.

DBG.txt has this to say:

[Sun Apr 18 02:36:18 2010]00033:*** WorldAuthenticate.  Error connecting to ezserver.getmyip.com:9000.
[Sun Apr 18 02:36:18 2010]00034:*** ERROR: WorldAuthenticate has failed establishing the connection.

I had this problem as well.  The bug cleared when I changed for SoF client to Titanium.

Casual Fridays has just been created.  We are recruiting anyone that wants to do more than they can by themselves.  Send a tell to either Elaith or Morphius if your interested.
