Here's what I've got.  I have a stored proc that deletes my old backup files based on the date/time stamp in the filename.  I also have a stored proc that PUTs the date/time stamp on the file name in the first place.  AND, I have a stored proc which builds RESTORE statements for all the transaction log backups according to start and stop time parameters, and based on the date/time stamp on the filename.  If you think any or all of these may help you, send me a private message with your e-mail and I'll be happy to send them to you.
