Obviously, the easiest way is to use a Master Ball, but you can only get one of those per game. So, the next way would be to stock up on Ultra Balls (like 100, you need a lot) and get its HP down. Then just keep using the Ultra Balls on it.
if you want to try to catch the legendary pokemon with a poke'ball, you must lower it's HP to red and give it a status problem (like sleep or paralyze)
Warning: If you poison or confused the legendary pokemon and you fail to capture it, it might faint.
only latios and latias

The legendary forest Pokemon would most likely be Celebi. As well as being the time-travelling Pokemon, Celebi is also a protector of the forest - most notably Ilex Forest (in Pokemon Gold, Silver and Crystal). No other legendary Pokemon is linked to any forest in such a way, so Celebi would have to be it.
The PokeWalker allows you to walk with a select Pokemon from your copy of HeartGold and if you walk enough, you can capture extremely rare Pokemon (though not legendary).
It is not required, but if you are willing to collect all the Pokemon, then it would be good.
follow them and then capture them
