Few questions about 2. rb quest

I wonder how many soul aroma, dream gras and moss we need 2 do 2. rb.
And can we do all quest without rbing and so sell the item so people just need 2 use this one item i sell to 2. rb ?

Anybody can enter the RB2 quest as long as there teamed with a RB1 to get in.
Once in, you can quit the team.

i hav no idea

You need 117 each. non-reborn and reborn below 120 will not get the 3 quest items as drop.
