I think I've answered most of my own question and I found  these configuration steps are identical to making the changes for an RS Native mode  installation. I guess I was hopeful after reading the documenation there would be a better way to accomplish the changes. This may be different for those running MOSS - as this pertains to Sharepoint Services 3.0.

My main goal was to change the list of Export filetypes and remove  the ActiveX Print Control.

Modify the List of Export File Types

Directly modify the rsreportserver.config file located on the RS server in the Drive \MSRS10_Instancename \Reporting Services\ReportServer folder. The drive\folder you set  during initial installation of report  Services so it will vary.

Find the section for <Render> and locate the <Extension Name=….> you want to modify and add Visible=”false” within the />

Removing the Print Control

Fire-up SSMS and select connect to Report Server – in RS-SQL2008 you access  some settings  via SSMS – and to connect you enter the full URL to the RS reportserver,
http://your.report.server/reportserver

Once connected in SSMS you’ll see the server name and under that Jobs/Security/Shared Schedules. Mouse over the server name and rt-click for the popup menu  and select Properties. Bingo! – you’ll see the “Enable Client Printing” checkbox towards the bottom of the General Settings...Check or Uncheck.
