Hello Cribbe, Umbraco is a very flexible CMS solution and will easily allow you to reuse content on other pages throughout your site.
As a starting point I would highly recommend you install my website wizard package from the package repository.
In v3 this can be achieved with an empty umbraco installation.
Goto the Developer Section
Right click Macros
Select Import Package
Click Open the repository (Recommended)
Select Website Packages
Select Creative Web Site Package
Then click download and install
This will give you an example site, which you can then look at all the templates, CSS, macros etc it installs to see how they all work together.
