Answer 1

For anybody using the integrated webserver that is built into SQL Reporting Services (and hence IIS may not even be installed on the box), the setting to control this actually lives in:

C:\Program Files\Microsoft SQL Server\
         MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\rsreportserver.config

Your directory may be different; version 10_50 maps to SQL 2008 R2.

You'll be looking for the setting called RecycleTime.
Default is 720 (12 hours). Setting it to 0 will disable.

Answer 2

I vaguely recall having problems with SSRS on one machine when we changed the "Enable HTTP Keep-Alives" setting in IIS. Try toggling that checkbox (I don't remember whether it was checked or unchecked when it caused us problems).

Answer 3

In IIS, check the settings on the application pool that SSRS is running in. On the properties pane->Performance tab you can set the amount of time the worker process needs to be idle for before it shuts down. You can also disable this entirely.
