Ultimate begininer questions (camera control / mouselook)

Good day folks. I apologize for being a toddler out of control with a crayon in unity 3d :) I am not a sophisticated software developer but I can program and I have been in the software industry for more than 30 years and spent more than 15 years in the gaming industry - so I am trying to reinvent myself.

I have a couple of questions - I built a mashup of the roll-a-ball app, two asset store packages for dungeons, a little bit of oculus integration and everything seems to work except for a couple of small but significant issues. I just want some help poking in the right place....

1. (and I know this is common) is my camera won't look up or down. My player prefab has a main camera associated and a custom script borrowed from many tutorials - the camera works in all regards except the mouselook aspect - it won't look up or down.

2. The network manager hud doesn't show up on the gear vr and I am sure its because of the worldspace vs camera space issue but I am not sure exactly where to find and fix that.

I know there are details lacking here - instead of spamming you with a myriad of useless details - just let me know what specifics I can provide to help pin this down. I know I am close :) I appreciate any general assistance now, and specific advice later.
