Your request can not be fulfilled in a simple post. I recommend you to start reading the Cisco SRND for guidance and understanding on how new networks are designed
http://www.cisco.com/en/US/netsol/ns656/networking_solutions_program_home.html
The new redesign in most networks is to have L3 inter-switch links instead of L2 inter-switch links to avoid any STP issues.
Please take a moment and read a couple of documents that matches your requirement and come back and ask more questions about 'finalizing' a design.
