Any meetup soon? question for Views + Panels 2 + CCK and theming the output

Hey, any Views and Panels 2 guru around, got a couple of questions for them.

for views: I want to know how "argument" works, seems it's quite powerful, yet I couldn't find any relevant post in drupal.org

for panels 2:

1. I wonder if I could use it to layout every blog node, and blog node alone, I know I can use panels to do "override" of individual nodes, but I want a panels layout for all the "blog node type", as the content of the layout may change alot, I want to have this panels solution over the page-node-blog.tpl.php theming one.

2. I want to use panels to layout different field of a cck node type, is that possible, while I read the issue queue back in 2007, ppl said it is not possible yet, is there any progress over the year? I think the solution lies in the use of the "context" and "argument" options within Panels 2, however, there isn't much documentation of how to use it. If there is a demo or scenario of how they should be use is very helpful.

3. how to theme panels page with CSS, any reference of all the div tag name in panels?

In addition, any quiz 2 module user here? And any module developer here? I need to develop some question type for the quiz module and expanse some quiz module's function to integrate with profile module. I need some direction.

Thanks in advance.
