Well, strictly 'proxy' means to only proxy reports from clients on to the 
display server, but in many cases the proxy is there to reduce the firewall 
access required, and typically this means that the proxy must do the network 
tests as well. If so, then yes, xymonnet and xymonnetagain should be enabled.

Yes.

In any environment with multiple instances of xymonnet, you should set the 
XYMONNETWORK variable in xymonserver.cfg on each server running xymonnet, and 
in hosts.cfg use the NET: tag with the value of the XYMONNETWORK variable of 
the server whose xymonnet task should do network tests for it.

This allows you to use the same hosts.cfg across all your servers (otherwise 
you are most likely to have diverging hosts.cfg files across your Xymon 
servers, requiring manual merging and updating of multiple files etc.).

Using the normal page, group, group-compress etc. statements?

(But, IMHO, it is wrong to mix the definition of what to test with how to 
present the display, it would be better to split them IMHO).
