Little tips to make life easier

You could use "equipslot"

/equipslot 14 Trinket of Awesomeness

would put your "trinket of awesomeness" in the second trinket slot. Here's a list of the trinket, ring and weapon slot numbers so you can enjoy the equipslot goodness that is available to you
11 : ring 1
12 : fring 2
13 : trinket 1
14 : trinket 2
16 : main hand
17 : off hand

If you're using the built in equipment manager, you can use the command:

/equipset <setname>

You can macro it as well, i.e.

/equipset [mod:alt] <set1>; [mod:ctrl] <set2>; <set3>

to have 3 different sets mapped to the one key.

For the quest starting items I just use the addon Autoitemstartquest.
You pick up an item and the quest menu pops up, you interact with a few times so all your alts loot.
Then I just click the accept button on my main.
