Ok, maybe you can figure this out yourself.
1. dbname = database name
This sometimes is pre-determined on some hosts, others have yourdomain_com_-_dbname. Or you may be able to create your own name.
2. I feel you shouldn't have a problem knowing your dbname & dbpass
3. localhost. This can be all kinds of different things. Most popular is "localhost".. or "127.0.0.1"
If you can figure out that information you should be alright. The rest is done through
PN's install.
There really isn't any other way to help you on this matter.
