Setting up posts & Beams

[polarbear]

In one drawing I need to set 4" round steel posts from ground to ceiling in rooms and 8" square wood posts from ceiling to roof. I would like assistance on how to do this.

I also have a laminated beam that is exposed (6.5" wide and 11"hi) on the ceiling between two walls. How can I set this up.

Thanks for the help folks.
