Answer:
2. To use the projector during the day time, or when there is ambient light in the room, you need to be aware of two things. Depending on the amount of light in the room (please post a pic)

3. The answer to this question is a matter of personal preference. It would depend on a number of factors, like the kind of channels you watch. If you watch NDTV then the big screen experience may be worth it because anchors like Nidhi Razdan are very pretty and deserve to be viewed on as big a screen as possible. But if you watch Republic news channel or (heaven forbid) TIMES NOW then you might want to consider as small a screen as possible since such channels only seem to show you images of angry people yelling at each other while having the temerity to call such cacophony a "debate" [= no eye candy and not worth it]. Imagine seeing a blown up imagine of General Bakshi frothing at the mouth while you are trying to eat (no disrespect to the gentleman whom I consider a fine soldier). Worse still, imagine looking into the maw of a yelling Na**ka while you are trying to unwind after a hard day's work.

BUT, here are some things to consider: Standard projectors use a lamp which has a lifetime of (depending on the model) about 3000 hours or more. If you want to use the projector for normal TV viewing, then you should keep this in mind. Replacement lamps can be sourced from the market, but there are a number of people who end up getting dud replacement lamps (they work but they are not as bright as the original, or they burn out within a matter of hours).
Because of these lamps, which are very high intensity, lamp based projectors can produce a lot of heat. Which will not be a problem if you are living in a place like Ladakh. But, if you are living in Ladakh, then I am guessing that the power supply will be quite erratic. Which brings us to the next point: The intense heat produced by the lamp also means that you need to follow the proper shut down procedure to prevent shortening the lamp's lifespan. Which means that you need to run your projector off some kind of power back-up device like a UPS or an inverter. Please factor this into your budget.
Lamp based projectors consume a LOT of electricity (on average 200 watts), which will inflate your power bills if you are going to use them for normal TV viewing.
Most of the disadvantages of lamp based projectors can be overcome by getting an LED based projector or a projector with a laser as light source. Please do note that LED projectors are not as bright as lamp based projectors. But most of them have a CLAIMED life-span of more than 20,000 hours. And they consume very little electricity.
Another problem with all projectors is placement. If you are going to use it regularly, then you are going to have to ceiling mount it, for which you would probably want to engage the services of a professional.
And... you are probably going to want to get a good quality screen which costs money.
If I were in your place, I'd just go and get a relatively cheap big screen TV. I'd save the projector for viewing movies and watching important matches.
