2nd Profession Changes

I have developed a w/e,which I'm very fond of-- however I have completed
the quests in Heroes Audience/Seekers Passage etc. which now allows me
to chose as a new second prof. one of the others such as monk/ranger etc.
MY QUESTION is once I change is the Change permanent lets say to w/m
or can I change back with all my skills and att avail back to w/e. AND if so
can I do it as often as I want to any of the other 2nd prof eg ranger or mesmer. IS THERE A LIMIT to the number of times or any Penalty associated with the change. And Lastly would the advantage of the changes if I can,
be for the ability to add as many skills as I can gather in each profession
- in the creation of a PVP character

you can switch any time you wish back with all skills that you unlocked. each time you switch you must do the quest, which isn't a biggie.

But how do you get the skills for your new sec. profession? All the quest that you have already completed to get skills are... well, completed. So I assume that you can't do them again, uless they are somehow reset? Any idea on that?

Eh? You sure? I only did the quest once and can change as many times as I want without doing the quest again.

You can get them from the skill vendors.

really? don't think I can...
Care to explain how you change it without doing the quest again?

EDIT: he is right, you only have to do the quest once. When you approach the NPC that gives you the quest, you can change it there anytime. brilliant!
