No, you are in the right spot.
1) Did you UPLOAD all the files associated with the install? There are several parts to installing third party add-ons. You have to upload the files that come with the add-on to your server (instructions are usually provided with the package), and then sometimes you have to run an SQL query (as you did).
2) If you have all the files in place, then have you added any attributes to any of your products yet? If not, you will not see any attributes to run stock against?
To add attributes to a product (like "Red". "Yellow", Small, Large, etc...) you need to first create the attribute name, then create the value.
You can do this by going to
Catalog > Attributes Controller
Ajeh has provided some great instructions on how to use attributes here:

Hope that helps!
