The SparkFun ESP8266 Thing is a relatively simple board. The pins are broken out to two parallel, breadboard-compatible rows. USB and LiPo connectors at the top of the board provide power - controlled by the nearby ON/OFF switch. LEDs towards the inside of the board indicate power, charge, and status of the IC. The ESP8266's maximum voltage is 3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC. That means the ESP8266's I/O pins also run at 3.3V, you'll need to level shift any 5V signals running into the IC. Also, with a little extra effort, the SparkFun ESP8266 Thing can be programmed using Arduino
A 3.3V FTDI Basic is required to program the SparkFun ESP8266 Thing, but other serial converters with 3.3V I/O levels should work just fine as well. The converter does need a DTR line in addition to the RX and TX pins.
