I started on guitar and still play it a bit, both plectrum and finger picking. On bass I use one or two fingers, occasionally a pick, and occasionally thumb and two fingers - for some reason I don't do thumb and three fingers like I do on guitar. There's no one right way, just be prepared to experiment with technique for each song.

He uses two most of the time, occasionally will use all 4 as one giant finger though. I mostly use two or a pick, though i would say it's worth being able to play with three, just because triplets are easier and it can help in faster sections, but it isn't an essential.
