1. You mail me after the purchase.

2. Should have no problems. You might need to add the switch in configuration.php

3. Of course.

4. Please install the free trial before you purchase and test everything. That way users shouldn't come and say "that and that doesn't work, I want my money back" afterwards.

ok,
i will get the trial.
before moving to mi final steps of gettns this amazing  comp
what about subdomains. 

A single license will only work on a single joomla installation and a single domain. No subdomains as they are different installations.

As stated before alias domains can be added.
