Can anyone answer these questions about live servers and the new expansion?

I tried this game on the tle a few years ago but the server was dead so I quit. I am also considering playing on the new origin server but I heard the leveling is atrocious and I'm not a fan of leveling in games really I'm more interested just in raiding. So I have some questions about starting as a newish player on a live server. If you can answer any of these or all of them that would be great thanks.

1-I'm pretty sure the new expansion includes a boost token to 130 but does that give you any AAS or do I have to earn them. Earning them would be fine since I would be at max level I can get into groups etc.

2-What is the current Max AA amount? I haven't found anything concrete but I think it's at 370 or 350?

3-how long does it take to earn an AA in a group setting?

4-does the new expansion include a set of gear that I can at least group with people to gear up for raiding?

5-What roadblocks/time sinks/would there be to me getting my character to be on par or close as powerful as the average character on the server so that I can raid and not be carried?

6-how long would those roadblocks etc take me to do given that I would be using a 130 boost token?

7-do I get all the previous expansions if I buy the newest one scars of destruction?

THANKS
