You will need to set up a dataset, and use a table adapter to populate that dataset with the particular data you want from your database.
If you have already made the database connection, you can drag tables from the data sources panel to your form and much of this will be done for you.
I can't help much in the way of particulars because I tend to use the wizards whenever possible. Also, I haven't been able to figure how to store the state of a radio button in a database (last time I tried was using VB6, though).
For expediency, you might try this site.

Here you will find an excellent series of tutorials. The one on databinding should help.
By the way, I'm a beginner too... just trying to help.
