Electrical Issue: Headlights

Electrical Issue: Headlights
Hello,
Just bought my first Land Rover. First, it's safe to say it's a project vehicle but only due to it being cosmetically challenged and the issue which I am posting about now.
Vehicle: 1996 Discovery SE7, 162k miles, Auto.
Symptoms:
1) Headlights will not turn on when combination switch is a turned to activate headlights.
2) Headlights WILL turn on only when I pull the lever back and HOLD it back. The moment I release it, the headlights turn off.
3) Turn signals work fine. BUT...I notice that it doesn't matter which way I turn the indicator both L & R indicator lights blink simultaneously on the instrument cluster.
4) Marker lights will not turn on.
5) L & R brake lights do not work: Only the overhead brake light works.
Checked:
All fuses are fine.
Not seeing any wires that could be shorting out
I've read a lot of threads where people have identified that the combination switch (headlight/turn signal lever assembly) needed to be replaced, but all of their problems seem to only be headlight related. I'm wondering if I have a relay issue and which relay it could be?
Thanks for any help provided!

Alright: Fixed #1. The Combination (dip) switch was bad. Replaced it and now I have headlights.
But......Taillights and dash lights are a whole other story. I only have taillights when I press the fog light switch on the dash. If I don't press it, all I get is headlights. No running lights at all. The rear has nothing that lights up until I press the fog light switch.
Also, I still don't have dash lights. Prior to changing out the combination switch, I had a blown sidelight fuse. Once I put in a new fuse, the tailight for that side turned on (but stayed on constantly unless I removed the fuse) and I had dash lights. But now that I replaced the combination switch and put the sidelight fuse back in, I have no dash lights. Crazy.
The brake light problem still persists. The only brake light I have is the overhead brake light. I did find that the passenger side brake light bulb insert (the white plastic piece the bulb twists into and then twists into the taillight assembly) had two broke tabs so it won't lock into place. I'm hoping that replacing it will resolve the issue.
Overall, I'm finding this Land Rover to be an electrical nightmare because nothing makes sense as to how it's wired up. Is there a relay or something that could be the issue????

Do you have the electrical manual? If not go here and download etlj960x.pdf

Then hope that the previous owner(s) did not 'customize' your vehicle.

Yep, the stalk (combination switch) was changed out for a brand spankin new unit.
But, I do have a follow up. The issue with the dash lights and the tail lights was a result of a faulty glove box light unit. Bought a replacement glove box light housing and it completely resolved the problem. Craziest dang thing ever. Love the mechanical build quality of this little SUV, but absolutely hate the way the Brits wired it.
As for the brake lights, I'm 3/4 of the way to resolving that problem as well. The passenger side brake bulb holder had two broke tabs (that lock it into place when you twist it in). Replaced it and voila! It works. The driver side is still puzzling me. The bulb holder is good and I've cleaned it out. The bulb looks good as the filaments are not blown. Thinking I may need to pull the tail light assembly out to get a good look at the contacts in it and make sure they're ok.
