A minor note: Any morale boost (Gained by killing bosses, accomplishing certain objectives in missions, and bought from deity statues) will also 'refresh' any spent res signets that the party may have used. If a partner drops during a boss encounter, raise them before you kill the boss.
Ctrl-clicking on practically any user interface item will give out a team shout, as well as executing that action as normal in certain cases. Some things to note:
Ctrl-clicking the health/energy bars will shout your current and maximum values for either.
Ctrl-clicking the experience bar will shout your current level and your percentage towards achieving your next level/skill point.
Doing either of the above will also target yourself, as will pressing F. Ctrl-space while targetting yourself will call out "I'm following (myself)", which may spur henchmen into doing the same. Best used when you need flight, not fight.
Ctrl-click/1~8 will shout out that skill, as well as target, and execute.
Ctrl-click a dead party members in the party window will call out that the person is dead. This may also spur henchman ressers into getting their thing in gear and to res that person, but don't count on it.
Even while dead you can still target/ctrl-call.
Ctrl-calling is the best undocumented feature in the game
Here be spoilers.

Though Alison the Tanner says that the only source for bear pelts is in Wizard's Folly, the bears in Regent Valley also have a (increasingly small) chance of dropping a pelt as well.
I believe the Althea solution for 'A Gift for Althea' is only available to prime/secondary mesmers. Mesmers also get an additional quest, 'The Rogue's Replacement'. I believe that prime monks (Not entirely sure) cannot get the 'Gwen's Flute' quest, though Gwen will behave as she would anyway had you completed that quest.
Something that may be useful following the Summer Updated: Gwen will give you a tapestry shard, a quest item for a quest that so far remains unimplemented. To get the shard, you need to present her with a new flute and cape from a merchant, as well as several Red Iris Flowers that pop up almost everywhere across pre-searing Ascalon.
