No changes; they all use one host certificate (this of the VOMS FQDN); FQDNs
of other two services are pointing to the same IP number in DNS

Regular YAIM configuration for MyProxy and LFC; for VOMS we have used the
standard scripts provided for its installation; note that PX_HOST can be set
to the FQDN of that service (which is just an alias for the IP number of
VOMS), while for LFC_HOST you need to set real FQDN (not the alias), and then
to define LFC_HOST_ALIAS to be equal to the desired FQDN of LFC service.

No.

No problems whatsoever.

Depending on the load of those services; VOMS certainly does not have high
load if you don't have 1000+ users; the load of MyProxy depends on the number
of submitted jobs that will renew their proxies (in practice we have not seen
problems with 1000+ jobs submitted in a row and consequently renewing proxies
at the same time); LFC load also depends very much on the way users use it (if
just through the command line, then no problems; if through jobs, then the
load can become heavier), but we do not see it currently.
All in all, you install services on the available machines, watch the load,
and if the load is to high on some of them, then you think about migrating
some of services on another machine :)
Hope this helps,
