OK, you're coming from 5.3x rather than 6.0x.

Go to this section:
Upgrades from 5.3x
of this document:
http://tetrabb.com/documentation/WebBBS/index.cgi?page=1;md=read;id=2

There is a detailed list of what files/folders must be uploaded.

I can't see which files you uploaded, but certainly the new board is neither loading the correct webbbs.css stylesheet nor the icons - likely not the JavaScript either.

Please walk down each item of the upgrade advice and ensure you've done what it asks for.

Regarding the blind email not showing.
You've set

$DisplayEmail                = 0;

Here is it's meaning:
http://tetrabb.com/documentation/WebBBS/BasicConfigs.pl?page=1;md=read;id=82

Blind email is an alternate way of how emails are accessable, but basically is only a subset of email display.

$DisplayEmail is a way to hide the email stuff altogether, or limit it to registered users.
It must be enabled to get any of the email display options to work (display email, blind email, email-captcha)

Enjoy.
