The next thing would be to upload the firmware, as written here: http://docs.micropython.org/en/latest/e ... html#intro
The actual images are here: http://micropython.org/download/
The recent stable image is v1.8.7, today's daily build is 1.8.7.-623
The command would be:
esptool.py --port COM3 --baud 460800 write_flash --flash_size=detect 0 esp8266-20170108-v1.8.7.bin
Once you uploaded the image, you can connect to it using a terminal emulation program like putty, winscp, teraterm.
Be sure not to use flow control, and 115200 baud.
For file upload / download there are various tools available, of which rshell and ampy seem to be quite popular.
You can also connect through WiFI using webrepl, which can be found here:https://github.com/micropython/webrepl

I don't know which terminal emulation program you are using, but it is essential to set 'flow control' ti None. This is done e.g. in Putty in the configuration pane under connection->serial.

These steps are fine. Only the port in Putty may be different than COM3. You have to check, for instance with the device manager.
And WIndows has the bad habit of changing COM port numbers some time, especially when you use a different USB plug.
