Can run LUA NODEMCU

Hi all,
#noobHere
Noob Question. I have a ESP8266-07 and Ive been able to flash the LUA Firmware but when I start the esp8266 in normal mode I simply get a few garbage characters on the serial port and thats it nothing else..
The vendor has suggested that this chip requires GPIO15 to be pulled low to GND with a 10k resistor but that hasnt made any difference
My wiring is
USB Serial TX to ESP8266-07 RX
USB Serial RX to ESP8266-07 TX
USB Serial VCC (3.3v) to ESP8266-07 VCC & CH_PD
USB Serial GND to ESP8266-07 GND & to GPIO15 via 10kRes
When I put it flash mode I am able get Mac addresses and flash no problems..
Q: Anything Ive missed??
Q: Does the latest firmware get flashed to 0x00000 or 0x7c000? http://benlo.com/esp8266/esp8266QuickStart.html indicates 0x7C000
Q: Do I need to reflash it to use with arduino code instead? (I plan to try this later tonight)
Any help appreciated.
Angelo
