You've already found the relevant info, well done. For a rough idea of the total power consumption in mW add the numbers in mA and multiply it by 4.1 (full battery in Volts). You only need to add up the numbers that apply. For example, you do not need to include GSM, GPS, FMTX, display on, MP3 playing etc, if you are not going to use them.

If you want Watts, devide mW (milliwats) by 1000.
