Just keep in mind that basic triggers don't provide any sort of flash control aside from a "fire" signal. You'll need a flash meter or a lot of trial and error work to balance your set-up.
Yes...with three or four lights, it helps to have all the lights be of the same general power at Maximum level, like say, four identical speedlights, or four identical monolights. Using IDENTICAL lights you can pretty easily use distance to make one light the main, the second the fill light, one the hair light, and one the background light. Identical lights will allow you to learn how one model of light performs, so your learning curve will be efficient.
A hair light or a separation light or kicker light, or an accent light, all of those three types of lights generally do not need to be very powerful in comparison to the other lights.
Manual-controlled lights, ones with a click-stopped slider, or rotating dial, or LCD readouts that give you Full, 1/2, 1/4, 1/8,1/16,and 1/32 power settings will make it easier to figure out what light needs to be set at what power level. Don't waste money
paying extra for TTL control lights when you're using a multi-light setup. Ally you need is MANUAL power control, and the dumber the lights are, the better; nothing is a bigger PITA than some light unit that "went to sleep" to save 1/100th of a penny's worth of battery power.
