Well since you're on Balmung and its currently not listed as Congested then limits will apply. You can move with 20M Gil (10m on your character, 5m per retainer by default) or more if you have 3+ retainers since each can take 5m maximum.
I have no idea about raiding and whatnot, though Ragnarok is the Legacy world here and i would imagine its where the bulk of the raiding community is.
