yes it moves
There's no specific spot to catch raikou because raikou is a wondering Pokemon it can go from route to route in kanto and this makes it hard to catch but all more worthwhile to catch it.
you have the best chance of finding and catching raikou(or any of the legendary dogs) on route 1.(use your master ball. raikou can run away.)
Route 1 believe it or not its true.
You catch Ekans on Route 4 in FireRed.
its on route 115 but you have to have kyogre,groudon and rayquaza
yes but you must get them on the pokedex first.(see them in the wild) then press start and if they are in the same route go into the grass to catch it.
After you defeat the elite four, Raikou and Entei run around Johto. (Suicune can be captured in Kanto.) Your first encounter with Raikou is completely by luck and chance, but once you see raikou once, you can keep track of what area it is in. again, Raikou can be found in every route in Johto, but he changes location each time you enter a building, go to a different route, or enter a city.
There are a few Jigglypuff in Route 3.
Suicune can be found anywhere where grass is the best route is route 1.
In Pokemon Soulsilver you can face Raikou at Level 40, Entei at Level 40, and Suicine at level 35. To catch Suicine youll have to chase him. Hell first be in Cianwood City, Then Route 39, then Vermilion City, then Route 14, then Route 25. Youll encounter him on Route 25 at Level 35.
no he just randomly appears but a super repel helps as only strong Pokemon would appear e.g. raikou
use good rod on route 19
