You'll need software to shut down the PC - most companies, including APC,
ship something with their UPSs, or have it for download on their sites.
Windows used to have a built in UPS application, but Server 2008 dropped
that.
Sizing the UPS will control how long you get to run without power. For a
typical workstation, a 500-750 VA UPS should be sufficient to give you that
long, though the VA isn't the only determinant of how long it will last, but
does tell you what load it can handle.
All UPSs will beep at you when the power is off. Some of them have software
options to disable that. But pretty much all of them have it on by default.
There are many other considerations when talking about UPSs, including
online/offline, true sine wave or not, and response time. Within a given
product line, you pretty much get what you pay for.
