bbPress by default tries to use your themes default templates as it’s base. So it is already using your theme’s page template, maybe not the particular one you’re after, but it will be for your theme, or one you have created.
It will look for the following files in your theme in this order, and use that for it’s forums
plugin-bbpress.php
bbpress.php
forums.php
forum.php
generic.php
page.php
single.php
index.php
See http://codex.bbpress.org/step-by-step-guide-to-setting-up-a-bbpress-forum/ for more detail and how to get it to use a particular template.
Since some theme writers create a bbpress template, and some have variously named page templates, it would be kinder hard to get bbpress to work out which of your themes files are page templates, and which you want to use.
Yes, getting the right template to display forums can involve you in renaming and moving some files, but that’s because you have decided to use a non-default theme (no criticism), and so your theme writer and the writers of bbpress would need to be telepathic to know how the other one is going to code. As I said some themes actively allow for bbpress, for others it is just one of thousand of plugins.
The plugin bbPress Tweaks
http://wordpress.org/plugins/bbpress-wp-tweaks/
In dashboard>settings>bbpress tweaks allows you to select from available templates as a dropdown, so partly achieves what you are after.
I fully appreciate that WordPress and plugins can cause a lot of frustration, and no you’re definitely not a troll (yet!), but less heaven and hell in your posts would be better!
