The order should be (I think):
Users
Forums
Topics
Tags
Replies
Agreed, this is necessary for large imports, I initially had a database of 110K+ users and 2.2 million posts/topics, which after 13 days of importing I decided to prune before attempting again.
In theory, you could rearrange these yourself by altering the wp-content>plugins>bbpress>includes>admin>converter.php file and changing the order of the steps. I actually thing the tags are the least important step for my site & the one that caused the most headache/issues while importing, so I made that step the LAST step.
