Just read this from page 1 and man this thread is unbelievable, if this is Kopitiam, I would think you're trolling everybody.

Regarding the bike's side mirror you can try changing to bigger side mirror for more viewing angle, try asking around at accessories shops. But usually aftermarket mirror such as Koso for example is smaller than the factory mirror on your zx150.

All vehicle have blind spot even cars, I would advise you not to get use to looking behind while riding your bike, you can do this occasionally only.
The reason is when you're looking behind you can't see anything from the front or the side which your head is not turning to.

Imagine this you are in between traffic. You need to make a right turn, so you turn on your signal and turn, right? Wrong, make it a habit to check your rear before turning because while you are slowing down, sometimes faster bikes/cars will overtake you. So now you need to check your rear, if you turn your head to look behind and at the same moment the car in front of you breaks, you won't notice it and bang shit happens.
My advice is learn to use the side mirror and take a quick glance to the side to check your blind spot when changing lanes or making a turn.

When you open your choke, the bike overflows your chamber with fuel to make it start easier. For optimum burning the bike needs fuel+air. If you open the choke for too long the burning might get too hot, hence the spoilt spark plug, worst case scenario is you might make a hole in your piston.

Lastly remember this the margin of error on a bike is smaller than driving a car, ride safe.

P/S : Why won't your bro teach you how to ride you bike ?

The no problem with getting a visor with no tint or clear visor. The only drawback that I can think of is when you're riding opposite of the sun and the glare lows your visibility, but this can easily be solved by wearing sunglasses.
Where else riding with a dark visor at night may be dangerous as it lows your visibility, some dark visor even states that it is not designed for night riding.

BTW your helmet can be installed with a flip up visor.

If you're thinking of getting a fullface helmet than get it, it's better than an open face helmet. You can also try a flip up helmet (not to be mistaken with a flip up visor).

Try asking for a fullface with a double visor, it's a fullface with clear visor but also come with a small dark visor inside the helmet which can be lowered or hidden with a button, see if it's your taste.

Regarding the choke are you saying that the bike won't idle with the choke turned off?
