I'm not entirely sure I understand your question.

It sounds like you're saying that during inserts the area that you want to query is locked while the inserts are occurring and you want to know what options you have for reading the data? If that's wrong, let me know.

You should look at using Read Committed Snapshot as the isolation level for your database. That will allow you to still query the data while the inserts or updates are occurring. It does add to the tempdb, so be sure you've taken that into account.
