In this scenario Cisco 2500 connected to several remotes via Frame Relay. One of the locations is experiencing bandwidth issues where FTP / or large e-mail attachments will starve the main application which is Telnet based. The default WFQ settings seem to be insuffiecent to cope, What would be a good setting to try on the WFQ side before attempting another method such as CBWFQ? The curent settings are default @ 64/256/0 I believe.

I think you might have to use class based WFQ for the issue above. The reason being the default queue for WFQ is depth in packets of each queue/maximun number of queues/number of queues which RSVP may reserve.
WFQ creats a seperate queue based on flows, the slower flows
get higher priority than faster flow. Telnet and ftp are both fast flows and if there are queued in two queues, the depth of both queue will be inherited from
the configured i.e 64/256/0. hence increasing this values will not
help your problem as the same queue dept will be used and inherited by all flows.
The solution is CBWFQ in which case we can allocate
bandwidth base on application. queue and dept are created
per class created w.r.t bandwidht allocation to the class.

You can achieve this by modifying the TOS value of incoming IP packets. Use route-maps on the incoming interface and modify the TOS value. WFQ flows are also based on TOS.
