I can't help you with the templates, but it shouldn't be so difficult to find.
There are two levels of permission control:
1. global (i.e. for all forums): you can set the permissions that somebody has to have in order to vote/write a poll/edit a poll. See the about page for an explanation of the permission levels. Like this you can e.g. only allow moderators or administrators to write polls, but everyone to vote.
2. If that is not enough for your purposes, you can issue permissions on a per forum/per usergroup level. This is done through "PollGroups" You can give a certain usergroup a certain permission in a certain forum, which will then override the global permissions (for that usergroup and that forum).
I hope this helps.
