Yes. You can read the documentation for instsvc.exe in a text file in the \doc\ directory. If you installed Firebird from the .exe installer, you only need to use instsvc.exe for a particular task in future.

Correct; and it is nothing new. As always, the C and C++ runtimes are also needed to run the Firebird server and any client. They are not unique to Firebird: they only need to be installed if they haven't already been installed by another product installer. vcredist.exe is the recommended way to install them (and I think the only way on Vista); but there are also copies in \bin\ if someone with Administrator privileges prefers to copy them directly to system32.

It sounds as though you haven't read the Installation Guide documentation (PDF) that comes with 2.1, either...
