If Varnish is on the same machine or on the same LAN, I would say to disable apache keep-alive since there is no real benefit to it. 
Regarding the timeouts, if you are referring to Apache, then probably yes, in Varnish you may want to increase the send timeout variable (/etc/sysconfig/varnish or /etc/default/varnish) since it can mess with large files.
