Joanna,
I'm sure Rob will be along with his advice. In the mean time I'll offer
my opinion.
I don't think you would ever regret going with 4 tubes. I think 20" is a
reasonable distance considering that you are only supplementing the
light from a big north facing window.
Here is a picture of one small part of my growing area:

I took that picture when I had one of the benches turned over to fix
something. I use 6 tubes spaced about as close together as I could get
them. I keep my plants only 6 to 8 inches from the lights but then I'm
growing in the basement and there are no windows near that area.
Mini Catts do very well with that light and it's not too much for Paphs
either.
Enjoy your new place!

What three types of lights are in there?
