We have multiple lists that users can subscribe to and one big list that we manually update periodically. Is there a solution for users to subscribe to one list and automatically subscribe to the big list?

If the multiple, small lists do not allow digests, or if digest subscribers are not a concers, you could set up the big list with no members and just include all the small lists in the big list's regular_include_lists. Then a post to the big list will be distributed unduplicated to all the current regular members of the small lists.

If you want members of the small lists to be able to post to the big list, you can also add "@listname" for the small lists to the big list's accept_these_nonmembers.

For the unsubscribe, can the users see all the lists that they subscribe to and choose multiple lists at once?

If you follow the above suggestion, no one needs to be removed from the big list. For multiple small lists, there is no "one click" multiple unsubscribe, but a user can visit and log in to her options page for any single list of which she is a member and click the "List my other subscriptions" button to get a page which lists all her subscribed lists with links to their options pages which she can then follow and log in to unsubscribe.
