Hello Rebecca, and welcome - yes, you seem to be getting the hang of posting messages ok You don't sound silly ha ha (or even peculiar ). I love rowan trees too, although I don't have one in this garden (yet), but if we lose our ash trees to this horrid disease we'll plant several new trees and rowan will probably be one.
To answer your question, rowan trees don't need a lot of looking after and they certainly don't need pruning (except to prune out disease, which is rare), so don't cut the branches.
Rowans don't usually need fertiliser either - in the wild they are at home on exposed hillsides where the soil is poor, but if you want to give it a little tlc as it's still a baby you could scatter some chicken manure pellet fertiliser around - this is a good time of year to do it, and the rain will dissolve it and wash the nutrients into the soil.
I'm not sure why the branches are growing in the way you say, except that rowans don't usually grow in a symmetrical way so it may be that it's growing perfectly normally. It's hard to tell without a photograph - can you take a photo and post it on here?
