I appreciate that you enjoy all those things but they're standard (as defined by a certain other MMO giant) fare as far as things go in the MMO world. People expected more content to keep them more involved in their character's storyline. Something class specific preferably. Bioware promised as such, but like many things - haven't delivered. Other than that, I've found that just making an alt is probably better for people complaining as you get to experience another story.

Pretty sure you can't. Although I haven't tried... simply put, why would you bother? It's a private area and they wouldn't be able to do anything there at all.

Pretty sure you're in the clear. Crafted items are separate entities once crafted. It wouldn't make much sense for an item you make for a friend to just stop working if you dropped your skill.
