yes, agreed, buy a separate power supply capable of 1A (300ma is sufficient if its a very good power supply) for powering the ESP and use only the TX - RX - Ground pins of the FT232RL (don't connect V+). Make sure everything is 3.3V @ the ESP

So, the following configuration is sufficient for boot-loading and running?
Esp…..Serial
TX0…..RXD
RX0…..TXD
GND…..GND
VCC to external power supply….. VCC left unconnected
REST…..RST
GPIO0…..DTR
Esp…..Serial
TX0…..RXD
RX0…..TXD
GND…..GND
VCC to external power supply….. VCC left unconnected
REST…..RST
GPIO0…..DTR

But here Esp VCC has been connected to external 3.3V power supply. Then why VCC has also been connected to the same 3.3V of the external source??

You can wire it that way, but I only use rx,tx, and ground on my setup.
