Hi Mahomed,

 I just know an answer about the last one ... I hope the rest will be answered 
by others.

If you want your skin customizations visible on the login page, too, then you 
need to make sure the anonymous user can view the page with the modifications.

Giving the XWikiAllGroup view permisisons is not enough, but you are in the 
right place; if you look at the top of of the list showing all groups and their 
permission, you should find a button to switch from groups to users - there you 
can give the "anonymous user" view rights, too.

This should work, unless you have secured the wiki in the adminstration with 
the "black checkboxes" preventing any anonymous access, independent of view 
rights.
If you have done the latter, then the wiki content is fully protected, 
including skin customizations, and unfortunately you cannot have both a wiki 
completely closed to anonymous visitors and still have them view that single 
attachment on the login page;
you would have to patch things by editing the webapp on the file system 
directly.

Cheers
Clemens
