I know this is going to sound crazy for asking these questions but I have to anyway.
1. Is it to late to start playing this event?
No. Go to the Shrine of Spirituality in Ilshenar, and either take the Bane's quest, or start killing them.
I'm pretty sure they are going to be the bad guys, or at least working for the bad guys, so I'd vote for start killing them.
If you want to take their quest, I think you'll have to kill Meer to get loyalty, not sure if killing Ophidians still works.
Killing Meer is not something I'd recommend.
2. Is this something I can do solo?
Most certainly.
3. If not do I need to be in a guild or just go with a group?
See above.
4. PLZ be easy on me with your answers..
Trammie noob.
Just kidding.
Sad that U-Hall has gotten so out of hand, with a combination of out-of-control aggression from some players and needlessly stupid questions from others (or in some cases some of the same players) that you feel you need to ask for "leniency" for asking some pretty reasonable questions.

EDIT: Also you may want to start attending your shard's EM events, especially if you're on Great Lakes.
