You can use the blocks admin, use blocks already there or make custom ones.
admin ---> system admin ---> blocks
To display various blocks on your home page or other pages in your site.
Also remember group permissions too need to be set.
Admin ---> system admin ---> groups
You can change the selected module as your home page module, for example you may want the forums as your home page rather than news.
Admin ---> system admin ---> preferences ---> general settings
You will see a option in there to set which ever module you like as your home page.
You are only limited by your imagination
I hope this is of help to you
