No worries about centring the image -- I saw your page last night and thought I'd help getting the photo centred. Note the American spelling of the attribute -- "center". The mediawiki code was developed by US coders ;-).
The reason the email title doesn't appear is to avoid repetition in the infoboc, otherwise it would appear as Email: email <link>. Its better to have the link appear as "email" rather than the actual address to limit scraping of email addresses from the wiki pages.
Great to have you on board & welcome to our WE family.
