That could very well be the case, I think I am riding a little nervous on a new bike. I've been hoping it'll wear off but it hasn't yet.Some of what you’re describing sounds to me like you’re too far over the front of the bike.
You sound more uncomfortable than someone whose suspension isn’t tuned quite right.
A long stem sounds very much the wrong advice.
I also don't think a longer stem will help. I had great trouble getting the front of my bike to hook up. I tried a longer stem first but it didn't make a huge difference. It was when I put a -17° stem on it that it came good. That lowered the bars by 10m, but didn't change the reach by much. Don't take that stem angle as gospel though, we've got very different bikes.A long stem sounds very much the wrong advice.
Forks need bedding in that could definitely be it.I also don't think a longer stem will help. I had great trouble getting the front of my bike to hook up.

I'll agree with the Rockshox needing bedding in. Mine were terrible for the first 6 months.
