hmm, wouldn't be as easy.

for checking if someone is a member you have to require global.php and then do an if conditon $bbuserinfo[userid] > 0.

as for saving files of direct linking, there's no way.
but you can use a trick, instead of give out filelinks, use a php file wich makes a "hidden" forward to the file.
i don't know if it would work for all files, i just used it once for images
