Answer 2

well..

I can't tell you where to find Mew in Fire red (because it's not there >w<)

but I can tell you where to find Mewtwo :). Mewtwo is found at the basement level of the Unknown Dungeon. You need to fix the Time Machine in Island #1

to access the Unknown Dungeon. And about Mew.. you can find it in Pokemon Emerald. The Old Sea Map in Emerald allows passage to Faraway Island,

where you will come across the elusive Mew in the forests. Chase it, corner it in the grass, and you'll be given the chance to capture it. Mew comes at level 30.
