How many watts do we need?

The number of watts you need depends on:-

The number of people in the audience (because bodies absorb sound)
The size of the venue
Whether you're indoors or outside (you need more power outside)

What you're amplifying (just the spoken word or a heavy metal band)

What does watts RMS mean?

The power or loudness of a PA System is measured in watts. Speakers and amplifiers always show the wattage in the spec (e.g. 300 watts) and the number of watts can be shown as Peak power or RMS. Peak power is the maximum it's capable of, RMS (which stands for 'route means square') reflects the average amount of power it can comfortably and continually produce for a long period and is the rating you should always go by. Always go with as much power as you can afford. You shouldn't have your PA system turned up to its full capacity because any peaks may cause distortion, and your speakers will have a longer life if they're not always running at their maximum.
