David,
It's probably a good idea to talk to your host about what you are installing, the size of your email lists, how frequently you will be mailing them, etc. It is also useful to know if there are any hourly or daily limits on outgoing email that might impede your mailings.
Other than that and if your host won't help you out with the
instructions provided, yes, I would say you're in great shape for an installation.
Regards
