Yes, you must complete the "Swan Song" quest and have a fishing level of at least 62. You also need a small net in your inventory.
An easy way to get 1 mil is to fish 2000 monkfish.
sadly no, you have the fish them all the way up in the Piscatoris Fishing Colony.
The Piscatoris Fishing Colony is one place I am sure theirs more out their you just gotta ask people.
160 Lifepoints.
Depends if you have money sharks if not monkfish.

That Entirely depends on how many hours a day you play runescape.
The best place to power-fish is at Shilo Village ( if you can somehow gain access ) since this is really close to a bank you can lure fish and it will be fastest way of gaining some levels as opposed to Monkfish.
