If you are installing it from Microsoft website then the answer is Yes. Microsoft will ask you to pass validation. If you have a stand alone copy of it, then you have to disconnect your PC from internet and istall it, in such cases it's better to have firewall (windows firewall doesn't work in such cases).
No, it doesn't. You have to update the installer from the Microsoft website.
In the correct conditions, yes. Some of these conditions might include things like: making sure the copy of windows xp sp2 that you use does not have any problems or troubles operating.
if you haven't upgraded your xp to service pack 2 yet you need to go to Microsoft.com and then it will search your computer for updates to windows and it will give to you a program called windows update which checks for future updates to windows and you can set in its prefs to automatically update or to notify you to. and windows installer is part of the sp2 upgrade. just follow instructions at Microsoft and give it permission when it asks you to install things.
If you mean an installation package, the answer is yes. It is called slip-straming. If you are talking about burning an installed copy to a CD, the answer is no. You can install on a USB drive though.
