In your solution explorer window you'll find a References folder. Right click it, Add Reference, then from the Browse tab you can browse to your dlls and add them.
Alternately you can do it from Project -> Add References.
If they are not compiled and are in source code format you could right click your project and Add Existing Item and then add your classes (or Project -> Add Existing Item).
