@jugularbean Re #1 – thanks for clarifying, just had to make sure 
2. You don’t change the filenames, you replicate the file/s and rename as header-buddypress.php etc and should be saved in root of your TMA theme folder.
You’re in luck. We can use the second method to make TMA compatible with BuddyPress.
1. Open up TMA’s header.php with text editor and Save As > header-buddypress.php in TMA theme folder
2. Open up header-buddypress.php and add the following at the very end of the file:
<?php global $woo_options;
//get_template_part( 'top-banner' );
?>
<div id="post_content" class="column span-14">
<div class="column span-11 first">
Save file.
Note: if the global woo_options wreaks havoc, delete from the code
3. Open up TMA’s sidebar.php and Save As > sidebar-buddypress.php in TMA’s theme folder
4. Open up sidebar-buddypress.php
a. At the very beginning of the file, insert
</div>
b. At the very end of the same file, insert
</div>
Save file.
5. You might want to tweak the default styling of the BP template files. You can use the following style changes used in Twenty Ten theme as a guide http://codex.buddypress.org/theme-development/theme-dev-bp-template-pack-walkthrough-twenty-ten-bp-1-5/3/
