I really, really don't want suggestions from my contact list to come up when I address an email. This could sometimes result in a disaster if I were to click on one of those names by accident and send the email to the wrong person. How can I disable this feature?

When you add a contact to a group you choose the email address that you want to add to it and not the actual contact.
When the contact are displayed in the group list you will have the email you have chosen and +x depending on how many other email address the person has, however, when you send an email to that group it will be only sent to the email address you have added to the group, not all the emails belonging to the contact.
Click on "Add BCC". Paste the email ids from to: field to the bcc field.
