IIRC X-rays form around 25KV, and tend to be fairly weak....Unless you stand closer than ~2 feet from it for a looong time you probably are not getting hit with a dangerous or even measurable amount X-rays.
The bars are likely a symptom of the set's designers not adding DC restoration to the video chain....There are period articles on how to add DC restoration you may want to look for.
It looks like your set has got case of the cone heads... The height and vert lin controls could probably use a touch up.
On the HV there are a few solutions. A roughly 3KV IIRC pF rated cap (or change in the cap's value) across the damper tube will change width and HV, reduction of HV winding turns will reduce HV, a resistive voltage divider may be possible with HV rated resistors, it may be possible to load it down with resistors or something like a 6BK4 HV regulator tube, but that could strain the flyback if it draws too much power.
GET an HV PROBE before trying any of this! You need to know how close you are to spec before tweaking! If the HV is within 4KV of spec you are probably best off leaving well enough alone.
