No, your amp draw will not be reduced. It will actually be slightly higher because the transformer will not be 100% efficient. Contact TEMCo Phase Converters at (800) 613-2290 if you have any more questions.
Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts. If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
It depends on the load. A good transformer has over 90% (some as high as 99%) efficiency. So the power drawn by it is a function of the power in the load, plus a small amount due to losses in the transformer.
If the load you are connecting to the transformer uses 1.5 amps or less, yes.

No because the current rating of the transformer is a maximum allowable current. If the computer still takes 3.42 amps it will be OK provided the new transformer supplies the correct voltage.
No; drawing more than the rated amperage from a transformer will cause it to overheat.
The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
50 amp
As your static pressure increases your Amp draw will drop
No because that transformer can only supply a ½ amp so it would seriously overheat if a 1-amp load was connected to it.
The lamp uses 240 x 4.9 VA, that is 1176 VA, so a 15 kVA transformer, which is 15,000 VA, could feed 12 lamps.
