it looks like you have a Musicmakers bouzouki kit. I made one of those a few years ago as a demonstration. From what I can see, you're doing just fine.
I don't know if you know this, but Musicmakers has a forum of their own where you can post questions and have them answered by the people who actually make the kits. The URL is:
http://www.harpkit.com/phpBB/index.php
The nice thing about this forum is that you may see posts by other people who have made the same instrument and therefore be alerted to problems that you may encounter down the road. And your own comments will be useful to those who make that same kit later on.
I check on that forum from time to time myself, and will chime in on any questions you may post there if I feel I have something to add.
