I am extremely new to SWT programming and it has been a while since I have done any Java/Swing programming as well.

I need some help getting my feet off the ground.
The application I'm writing the users will need to log into a 3rd party application. Once logged in I want to display a main window. The main window will have several search buttons that query the 3rd party application.

I'm wondering the best way to structure this stuff.

Should I only have one loop that looks like this?

while(!shell.isDisposed()){
    if(!display.readAndDispatch()){
        display.sleep();
    }
}

... or should I do that for the login dialog and then after the login shell is disposed I create the main window and start another loop like this?

Also, how am I to get values back from dialogs? Like if my login dialog creates a session object. How do I get that back? Or get back my search results from a search dialog?

I get compiler errors like this when I try..

The final local variable session cannot be assigned, since it is defined in an enclosing type

Final variables can only be assigned by initialization, or in the constructor of the class owning the final variable. I don't know what enclosing means here, but it sounds like you are trying to assign it from a local class.
