ACT:
Advanced Combat Tracker -- An Encounter Parser for EQ2
Poisons, especially in groups: Use red Caustic or red Hemotoxin. Purple: Use Grace or Enfeebling (Enfeebling will become your AA-enhanced friend). Blue: Use Turgur
Other poisons can be used while solo-ing, or in special situations - you should study them. Mentral strike (red) can be useful when power issues arise.
At lower levels, I wouldnt care too much about adornments (actually I also dont care much at higher levels), besides getting a few cheap ones.
Weapon: if you have one really good weapon, single wield with WIS line. If you get two really good ones, start DW'ing. After lvl73ish, DW is the only way to go.
Fot the rest - study the 101.
