This is potentially a massive question, and the consideration of the load balancing hardware and using SSL off loading would suggest your environment is clearly more then 10 users on one switch.
I would suggest you consult a network consultant after deciding your end target of what you wish to achieve, and discuss it with a few to getting further ideas.

As a rule of thumb I would suggest a separate VLAN for each sever type (web, mail, application, file sharing etc.) and consider carefully how you wish to segment your users.  Just because they are in separate VLANs does not mean they can't access each other VLANs including the server VLANs.  Basically you're creating broadcast domains and if one was to be compromised by way of DHCP starvation, broadcast storm or some other action caused deliberately or by accident.  Separating users, even sitting next to each other will ensure such a condition will ensure some people still work.

Is there wireless and voice considerations?
What are your security considerations regarding access to different parts of the system?
What industry are you in?  Are there restrictions due to the industry such as retention of user data and controlling access to it?
You really need to break you questions up.
