Reddit mentions of SparkFun FTDI Basic Breakout - 5V

Forgive the 100% newbness, but I'm thinking of doing this as my first electronics project (I'm a software engineer by day).

I created a slightly different parts list through adafruit.com here: ESP8266 BTC ticker parts.

The main differences are:

• Instead of the FTDI Basic Breakout, I'm hoping to use the FTDI Serial TTL-232 USB Cable
  
• I swapped the Monochrome 0.96" 128x64 OLED for the Monochrome 128x32 I2C OLED
  
• I couldn't find 330 ohm resistors, wondering if 220 ohm or 470 ohm would suffice?
  
  Do you think I could work through the tutorial with my altered parts lists? Also, how to power this device on its own? Should I purchase a battery as well?
  
  Thanks for any help in advance!
