I can help a little and suggest some things, but I don't think I've seen this before with gallery...
First, the last 4 warning/error messages about the headers already sent can be ignored since they are just a result of php sending the first error message (once anything is written to the html page headers/cookies can't be set).
The first error may be fixed by removing:
$GALLERY_BASEDIR .
from line 30 of view_album.php. It looks like maybe your php security settings are not allowing you to use uninitialized variables (don't ask me why gallery uses them in the first place).
If removing that doesn't help try replacing it with the relative or absolute path of init.php. i.e.
./init.php
--or--
/var/www/moocrew.net/public_html/gallery/init.php
Good Luck,
Vinny
